Better bring your own... not sure what your tastes are, I do have everything from Simon and Garfunkel to Ministry, but most of my collection is punk (interested in the message more than the medium).

Though my favorite speaker testing songs are Whatcha Need (Bootsauce) and Dead Souls (Nine Inch Nails) I've also got a few CBC reference CDs for things like tone and pink/white noise.
