For singles: Albums is not used at all, but it still need a correct File Mask, examle these:
mp3/Artists/Title.mp3
mp3/Artist - Title.mp3 (no folders)
mp3/Artsits/Album/Artists - Title.mp3 (but it actuelly do not use album).
You just make sure artists and titles is on the same place in your filemask structor. If you dosent have any real file mask, like above, you need tag them all as version id3v2.3 tags (DONT use id3v2.4, or it might crash MultiJuke).
I also highly recommered to have a good file mask, since you can mass tag them in that way, based on a File Mask. EVEN if you dosen't use albums.
Otherwice you can use Explorer Library. In that library system, it simply show them as you used MS Explorer to navigate your songs.....
For karoake:These is a special cd's that have graphics on the audio cd as well, which used a subchannel to contain graphics data. These cd can been played in a regular cd players to play audio, but to show the graphics on the cd, you need a special cd karoake player, that can show the graphics to your television to show the lyric.
In typical Jukebox software, that graphics is ripped as a CDG file and need to been the same file as the music file itself, also it splitted into 2 files each song.
In MultiJuke, these 2 files can been zipped, because CDG files can been compressed very well, but freebox can support this format too, but not in zipped form.
