Will you people please stop using myspace as a link to your songs that you want critiqued? Myspace sucks, and you're not doing yourself any favors by having your music mangled by the myspace player and then having someone else try to decipher what actually sucks about it. There are SEVERAL FREE MP3 hosting sites out there on the interwebs that will allow you to upload a high-quality 320kbps MP3......unless of course you're just looking for "hits" on your silly myspace page.
Use your head and your google and find a free MP3 hosting site that allows high-quality MP3s.
Mix your song down as a HQ MP3 or a wav and convert it. Simple.
Here's one that I use all the time:
