R63B - Jukebox own Music? (Song_data help?)

[Pascal.de]

Hello Guys,
I have a R63B revCMS Retro with BCStorm Emu.

I want to Import my own Music to the Jukebox. I made a mp3 (10 sec.) and renamed it into sound_machine_sample_800
Then I went to my Database and replaced all sample number from song_data to 800.
It worked and I can hear my own Music. BUT: I hear it more times at the same time?
When I write 1:800 to song_data I cant hear anything? (So I replaced all)

So my Questions:
1. What do I have to write into song_data to Play the song ONLY 1 Time?
2. Which lenght can the mp3 have? (30 Sec.?)

Thank you :)
