Off the top of my head, the collection includes: Alice Cooper, Ted Nugent, Judas Priest, Journey, Styx, Foreigner, The Beatles, The Who, Black Sabbath, Ozzy, Van Halen, Led Zeppelin, Men at Work, Fine Young Cannibals, The Cars, Rush, Santana, Aerosmith, The Village People, The Band, Toto, Berlin, Michael Jackson, Blondie, Pat Benatar, Pink Floyd...
And the list goes on. Yep, vinyl's back, but you can still find great stuff out there "in the wild" for only a buck or two. I think the most I've paid is $6, and most were under $1.
