Issues With Music Replacements

[Juri Han]

Alright, so recently, I've been having a problem that I'm hoping can be solved, because this one is really annoying.

Basically what I'm getting is a sped up(?) song which kicks in about 2 minutes into a regular track. For example, I was playing on Green Hill Zone, with Endless Possibilities playing, and everything was fine up until that 2 minute point. After that, another song from my SD card will start playing, and it'll usually be sped up to the point where it's almost distorted.

Luckily, I found a YouTube video that was showing the same problem.

I've been searching around for an answer, and I've found two possible solutions. It said I can either:
-format my SD card and put everything back on there
OR
-My card is likely messing up because of how much stuff is on there. I currently have about 12MB on my 2GB card.

Anyway, if anyone could help, I'd greatly appreciate it, as always.

Sound quality can also be an issue.  Brawl uses BRSTMs with Sample Rates of 32000 Hz.  BRSTMs with higher sample rates (Ex.: 44100 Hz or 48000 Hz) may behave erratically if used in-game.

Yep Chuy is right. I had the same problem recently and formating my sd card solved it  :)

Yep, turns out that's what it was. My music tracks seem to be working properly now ;D Thanks for the help, guys.
