Joan Jett and the Blackhearts - I Love Rock n Roll on vinyl
I agree with what GSRIDER said in 
this thread, Joan Jett is freakin' awesome.  A real rocker chick.
 
Can't remember the first CD I bought.  I've lost or damaged so many of those over the years.  I should call the RIAA for a refund.  Last one I got was Live - Birds of Prey.
And cassette, no idea.  Probably wouldn't admit to it if I could remember.  That bad.
