Hello,
I have add new music into the "music" directory from the game, i have erase all tag from the new music i input and i have tip the same tag as the original music (exept track number) but, in game when i change music, the game skip all of the new music i have put in the game folder, why?

Have a configuration file to modify for making the news music files working?
PS: Sorry for my bad english, i speak french.
Thanks in advance for the answer.
first of all this post "belongs" in "Longbow Support" section
either way i'm here to help :)
this is a music format issue, and as far as i know TM doesn't even use tags so you shouldn't worry about them
all i know is this problem has to do with three things,
1) frequwncy or hz EG. 44100
2) bit rate 64-320 Kbps
3) the type of mp3 (varible, constant, speaker type -mono stero etc.
to ensure best compatibility your mp3's should be in:
hertz -= 44100
bitrate - 192
speaker channel - stereo
you can try converting your music with a program like winamp but it may not be easy if your not good with computers.
this is a common issue with TM's outdated mp3 playback system
*personally in rick's next TM update, he should make ALL mp3 types 100% COMPATIBLE*
thats all i know about fixing that problem, as i had the same problem with fraunhoffers newer mp3 format, i tried everything and "only" this worked for me.
