1. How to select tracks for playback

You can select tracks for playback in three ways:

  • From main screen choose Play folder option, which will open file browser, where you locate folder with your desired music files. The browser displays folders on both device memory and external memory card. Typically you'll use memory card to store music files, but you can use internal device memory as well.
    When you select a folder in the file browser, current play list will be cleared, and all music file in selected folder, as well as its subfolders, will be added into playlist, in the order as they are found.
  • Use playlist editor to load a playlist file. More about this in Playlist editor paragraph.
  • Add individual tracks of entire folders using Playlist editor.

2. Location of music files

You can store music files in any folder in device memory or on memory card.
Some operating systems, for example Symbian 9.1, have restricted access to certain folders, so if you send a music file to device by Bluetooth on such a device, you won't be able to open it using LCG Jukebox.
Ideal way to transform music to your mobile device is using USB cable or memory card writer.

It is best for LCG Jukebox to keep music albums organized in own folders on disk. This way you can quickly add entire album to playlist by selecting its folder.

3. Playlist editor

The Playlist editor allows you to manage your current playlist. It offers this functionality:

  • Save playlist on disk
  • Load saved playlist
  • Add tracks to or remove tracks from current playlist
  • Change order of tracks in playlist
  • Start playback of selected track
  • Permanently delete track from disk

The playlist editor can load and save playlist in standard format M3U. If you upload such playlists along with your music files, you can load the playlist in the Playlist editor.

4. Track information

The player reads standard ID3 tags from music files that support them. Mainly it reads artist name, album name and track title, and displays this information on screen. Additionally when you choose to display track details, you can read the year and genre information stored in ID3 tags. This player can read both V1 and V2 tag format.

5. Resumed playback

When you close LCG Jukebox, it saves current playlist into a temporary file including current play position. When you later open the player again, it loads this information and resumes playback in exactly same position where it was before closing.

6. Random and Repeat mode

In repeat mode, the playback continues again when last track of current playlist finishes playing.

In random mode all tracks in current playlist are played in random order. The random order is generated when playback of playlist starts, and is preserved when you close and later open the player again. If playback is finished and is to be repeated (in repeat mode), new random order is generated.

You can see icons on the main screen notifying when random or repeat mode is active.


LCG Jukebox helps in listening to audio books. If enabled, it remembers position in track (when playback is switched to different track), and automatically resumes playback in previous position when such file is played again.
Player can remember position of up to 10 tracks. Position is remembered only in tracks with lenght greater than 15 minutes, which are considered to be audio books, rather than standard song files.
Additionally, all files in Audiobooks folder are treated as audio books, and bookmarked, regardless of their length.
The operation of this function is fully automatic, and doesn't require any action from user. However, it can be disabled in Configuration.
If audio book is bookmarked, a bookmark icon is drawn next to its name in the Playlist editor.

8. Equalizer

10-band equalizer allows you to change characteristics of played sound by increasing or lowering particular frequency band.

You can choose one of predefined equalizer preset from either main screen or from equalizer editor. As you browse presets, currently selected preset is temporally applied so that you can hear how it sounds. Once selected, the preset becomes is chosen as active equalizer settings.

Additionally you can modify bands manually in Equalizer editor. You can choose band and adjust its position. There are also special Movement setting specifying how neighbor bands are affected when you adjust particular band, so that you can setup smooth curves with minimal effort.

9. Idle screen mode

The player can display minimized information on phone's idle screen. In this mode you can see artist / track title, time and few other information.

The idle screen mode is only for informational purpose, in order to control player (e.g. change volume or choose next track) you have to activate the player.

10. Sleep timer

Sleep timer allows you to specify time after which the player automatically shuts down. It's ideal for falling asleep with music played from your mobile device. When you start sleep timer, you'll see an icon on the main screen.

In last several seconds before the player is shut down, the volume is attenuated in order to smoothly finish in silence.

There's also a mode named 'Automatic', when sleep timer is configured to switch off player when current playlist finishes playing last track.

11. Album art image

LCG Jukebox can search album art image on the Internet. For this you need working Internet connection on your mobile device.

Please note that this functionality may download several tens or hundreds kilobytes of data and may incur you costs for transferred data. You should check with your mobile operator the prices and conditions of Internet access.

For this function to work, it is essential that ID3 tags of music tracks are filled correctly. The search uses artist name and album name and searches matching images on the Internet. You can also edit the search parameters manually and invoke the search.

Once the image is downloaded, it is stored in same folder as the song file, in format "[artist] - [album].jpg". All tracks in one folder can share same album image file. If there are multiple artists or albums in one folder, they use different image files, so the album art image should in all cases be displayed correctly.

If available, the album image is shown on the main screen, as well as in other modes, and you can also view the image in built-in image viewer.

12. Lyrics

LCG Jukebox can search lyrics (text files containing words sang in the music track) on the Internet. Again you'll need working Internet connection, and the download may incur you additional costs for transferred data.

The search is performed on several servers displaying song lyrics. For this function to work, it is essential that ID3 tags contains correct artist name and track title. If search fails, you can edit search parameters and try again.

Once downloaded, lyrics are stored in same folder as the song file, under same file name but with .lrc extension. They can be later displayed in the lyrics viewer.

Some downloaded lyrics contain timing information, so that they are scrolled automatically as the song is played. If timing information is available, small icon with clock marks this on screen. If lyrics do not contain timing information, you can use cursor keys and scroll the text manually, or you can choose automatic scrolling, then the text is scrolled smoothly during entire length of music track.

LCG Jukebox can also display lyrics embedded in mp3 files in ID3 tags.

13. Internet streaming (internet radio)

Additionally to playing local music files, LCG Jukebox allows listening to Internet streaming stations. The player supports Shoutcast and Icecast protocols over http. The stations are normal entries in playlist, but instead of local filename, a remote URL (internet address) is specified. Each such address begins with http:// prefix.

You can setup Internet radio station address in Playlist editor either manually by adding station (entering URL by typing it), or you can use Station manager to browse and keep your favorite stations.

In the Internet streaming mode you cannot view/download Album image (because there's no album associated with stream). However, you can still download and view lyrics. Internet streaming stations send information about currently played artist / song title, and this information is used when searching lyrics. Lyrics are downloaded temporarily, and persist until station changes to different title. A limitation is that there's no information about length of song, so you can utilize only manual scrolling with Internet streaming radios.

Note that Internet streaming may result in big amount of transferred data - check your possibilities with your Internet provider. The amount of transferred data is displayed in player's interface during listening to Internet radio station.

14. SHOUTcast™ station manager

With SHOUTcast™ Internet radio station directory, you can search among thousands of Internet radio streams by genre or name. You can type seached term - name of station, or genre, and you'll get list of stations with description. Found stations are sorted by lisener count, most listened at the top, and you can see station popularity by number of stars next to station name.

From this list you can choose desired station, and either start to play it immediately, or save it to your local list of favorite stations (also available in SHOUTcast station manager). A saved station can be chosen for playback in a future.

You can also search by genre - choose Search by Genre from menu, and you'll be able to choose from all genres offered by SHOUTcast directory. After choosing desired genre, matching stations will be again searched in the station directory and presented in a list.

Finally you can enter desired station manually to your local station list. When you add new station, you can enter station name, url (Internet address) of station, and optionally the stream bitrate.

You can export (save) your saved list of stations, and import the saved list later or on a different device.
