It's mostly crappy music, but on Slicethepie.com you can get paid to review songs.
You earn about $.05 to $0.12 per review submitted, depeding on how many of the elements in the song you talk about.
Once you hit a multiple of $10, you withdraw into your PayPal account.

If you're interested, I get a little kick back if you join under this link: http://www.slicethepie.com/?wyd=672559

Oh, and when you sign up, use your paypal address as your email so you get paid to your account.
