What are the ten greatest songs that were better as covers than the version sung by the person who wrote them?
To keep the list kosher, we'll confine the list of possible songs to those written by people who have had at least one song sung by them make it to the top ten. The song also must have been released in some form by the writer as well as been sung by someone else.
The first two people that come to my mind immediately are Carole King and Bob Dylan. I'm not a big fan of either of their voices, but they both wrote some great songs.
