Whenever I try to play a track that I uploaded, it plays at an incredibly quick speed, ending up a high pitched squeak less than a second long. The timecode says "0:00/0:23", which is both much longer than is actually playing, but also shorter than the file is. I've tried this both with a file I downloaded, and one I recorded myself. Is it a file format issue? I'm using mp3s which the wiki says are compatible.
