Rock Covers.com - a site that publishes amateur covers of rock songs. (Note to librarian-types: there is no authority control! A band that does a cover of Ash's cover of Ween's "What Deaner Was Talking About" is credited as doing an Ash cover, not a Ween cover!)
Covers of Ace of Base songs This list includes RealAudio files of covers that have been done of Ace of Base songs.
The Band. I don't know much about The Band, but boy is this a detailed, attractive website!
Covers of Leonard Cohen songs This is part of the Leonard Cohen site that includes all types of recordings of his songs, sorted by artist and song title.
Covers of Joe Jackson songs This site is very inclusive of Joe Jackson material, and starts with an index (very important to us Librarian-types). Includes RealAudio files. Hint: to find the covers, you need to start at the "A-Z Index".
Billy Joel. I'm not a big Billy Joel fan, but we Kenny Rogers' fans I'm sure appreciate his duet of "Just the Way You Are" with the late Dottie West.
Kiss cover versions and tribute albums. I'm a big Kiss fan, so check out specific songs in my covers section for more info/more covers.
Covers ofMarc Bolan/T. Rex songs. There's much more than "Get it On" by the Powerstation here ...
Covers of Thin Lizzy songs that have been recorded. Who knew there were that many Thin Lizzy songs! And that Huey Lewis did a version of "The Boys are Back in Town"!
Wreckless Eric. I loved Wreckless Eric way before I realized Cliff Richard did a cover of "Broken Doll" ...

Apparently Boney M has done some great covers. I love to hear a good version of "In A Gadda Da Vida" ...
Joe Jackson. This site is very inclusive of Joe Jackson material, and starts with an index (very important to us Librarian-types). Includes RealAudio files. Hint: to find the covers, you need to search the index first.
REM. This is a list of covers that REM have done from the REM lyrics website.
Covers done by the Rolling Stones This is a great site for Rolling Stones fans. It includes both covers done by and of the Rolling Stones and is very inclusive. (I give them points for having the Hot Rocks Polka medley done by Weird Al Yankovic!)
