Sound issues with SSRMAX and BMDX

[Zerosu]

Allright, I've got some official bmsfiles and whatnot, and some songs run perfectly in SSRMAX and BMDX, but I've got a few where the game doesn't play all of the background music. The songs in particular are era, Brilliant 2U, and Dynamite Rave. The songs also run just fine in Be-Pachi, so I'm completely clueless. Anyone have any ideas what the problem could be?

Same goes for me with some of my songs I have. I know one of them is SCREAM SQUAD.... Although I can't even get SSRMAX to work which is really too bad because it's the closest sim to the real thing.
