The Covers Project … building a database of cover songs (songs performed by an artist other than the original performer) with the intention of creating cover “chains.” A cover chain is a set of songs in which each song is a cover of a song by the band who covered the preceding song.
So far, we have 6,075 songs (4,188 unique) and 2,960 artists catalogued. The longest “chain” we know about contains 43 songs.
2017 Update: This website sadly appears to be extinct.
