When it comes to recordings of your favorite songs, do you insist on the original, most widely known and distributed studio-recorded versions (i.e. the definitive, historic versions), or does it really not matter to you? Are you equally happy with a live version (provided it's good) or even a later re-recording of the song by the original artist?
I tend to insist on original studio versions myself, unless a live version becomes definitive (i.e. the live version of Cheap Trick's "I Want You to Want Me" or Peter Frampton's "Baby I Love Your Way").
