To be honest a lot of the site looks like it was made in MS Paint.
The logo needs to tell a lot about the site. I made this just for the hell of it. You can use it if you want, but regardless, the current logo is really bad... I could make it in MS Word.
Aside from that... how you select music is a pain in the butt. It needs to be made far more easier and visible.
Look at sites like OCR, VGMix, Remix the Sauce... heck even places like Newgrounds and Soundclick.
The site needs a lot of work both artistically and from an ease of use standpoint. You need to assume everyone who visits your site is an idiot, and as such the layout needs to be presented in such a way that an idiot could get through it without much of an issue.
