Custom music for Europa Barbarorum is not looped

[Heterosapien]

I have added music from HBO:ROME TV series by Jeff Beal, but every time I play the music stops after one track. My problem is the old tracks (default EB music) still play looped but the new ones i added don't. So while playing i have to press ALT+M (which toggles game music on/off) every time the song ends to activate the next track.

I tried decreasing the settings at the top of the file descr_sounds_music.txt but that didn't help. There may be something under properties of my new mp3's that needs to be adjusted, because like i said, the default music does still play looped.

I have also tried renaming the Music.dat file, but it appears to be overwritten, or unchanged after i boot EB up again. There does not appear to be a Music.dat or Music.idx file in RTW/EB/Data/Sounds/music to begin with.

If i edit a file should i place it in folder "sp game edu backup"?
