RMXP isn't playing *certain* MP3s

[Kain Nobel]

Hello and good day!

To make a long story short, I just imported a bunch of finished tracks into RPG Maker XP and, for some unknown reason, a bunch of them simply won't play at all, not in the editor's music player nor in the game. All tracks are mp3, and the ones that do play work just fine, I can change the pitch and everything no problem. The ones that can't play, when called in-game, don't play at all and cause the game to lag badly until a working piece of music is called.

Before I had this problem, I had taken a bunch of tracks that were only in my "*/Music/" folder (as I play everything in my media player), cut and paste them into my custom RTP folder, replacing the ones that already existed. Prior to this, only a couple of existing tracks in that folder I had problems with, but now I have an issue with a majority of the tracks. Is it because I replaced them? I don't know :(

Last thing to note, these tracks do play just fine in a media player (WMP, QuickSilver, etc), I'm not sure if they play correctly in VX or VX Ace, but they don't play at all in XP.
