I've checked with the Music Modifier cheat with BK. Same problem... different tracks bunched up.
I think I know why. In the gameplay when you enter a level, all of the tracks play at the same time. The unneeded parts temporarily have a volume of 0. When you move Banjo to a certain area (ex: Underwater, near a certain entrance of a level), the console turns down the volume of the tracks you're hearing and turns up the volume of other tracks. This is a way to allow the song to play continuously when you change areas in a game (mostly with Grunty's Lair).
You can tell that the game is using the same soundtrack to play two different versions too. If the song continues to play when you go to a different room, the game is using the same soundtrack. If the song stops when you go to a different room, the game is using a different soundtrack to play the song in the next area.
I think I stated in my tags how many versions the songs of each game consists of. The grunty's Lair tracks may a be a repeat though (Because the versions are put in according to the level locations). BT will definitely have this problem too.
By the way, I just noticed that the tag set archives for BK are corrupted, I'm reuploading them now. I've uploaded Alex Lee's (is that you, Al-M?) so far, Agustin's is the last one left.
...Hmm. You sure the usflib is there? I downloaded the tagged Bomberman 64 set earlier and noticed they didn't come with the usflib, which I had to get from the untagged set.
Here's something to think about. Were you able to open and extract the files out of the archive? If yes, then they are not corrupted. If they were corrupted, then you would not have been able to open the archive. As such, if they're not playing, then that would be because you are missing the *.usflib file, which is where all of the music data is actually stored. In other words, you're missing all of the music, but none of the tags...
That's probably what happened. Read the FAQ, as that situtation happens often. Mouser X over and out.
