In the land of useless music trivia, the cover chain is king. Well, that’s probably an exaggeration considering the dearth of new VH1 behind the rock star’s dirty linens shows, but this certainly ranks among the trivial. Find artists who covered songs by other artists, then find other artists who covered the cover artist’s songs. Follow me so far? If you’ve ever had an argument with someone you know over who sang what, you may find you are both right, only one of them sang it first. Just flipping through some of the artist lists reminded me of music I haven’t listened to in ages. No audio is available on this site, just information. Now off to find that L7 cover of the Dead Kennedys classic, Let’s Lynch the Landlord.
