Having said that about the net, someone I know was approached by a music promo company, on the strength of his site content and popularity alone, to be sent free stuff. They gave him CDs all the time, and he got some phone interviews and gig tickets, absolutely free! All he had to do was review - which you want to do anyway! And the best bit is, you get creative freedom; say what you like about the artists, as long as you send them some form of review back. I'm sure specialist film sites get free stuff too.
