direct link?

i dont know if this is really a bug, or just me being an idiot, or simply a feature you dont support but my direct-links aren't working. i uploaded my mp3 and put the direct link into a music player and they worked for a little bit bot now they dont. when someone clicks on a link to a song it just brings them to the songs download page not the quicktime player. any help would be much appreciated as i am horrible when it comes to website stuff.
