Looks like a good start. Clean code.
Overall I'd say it just needs to be styled. I'd go with a sans serif font. Put DJ names as <hx> and change links from default to something else.
The contact page seems odd to have the submit button before the form inputs.
I'd visit listamatic for some other menu options.
I haven't downloaded any music so I an't comment on that.
It seems that this could have a little more something to the theme. It seems that the idea might be a little tongue in cheek that its (or at least looks like) middle class, suburban, Maryland boys doing dance/hip hop remixes. I'd suggest having fun with that. But, I could be reading it wrong. Maybe its very serious dance DJ-ing. It looks a little sterile.
