This first one is mildly amusing (I especially like the Coldplay part), http://www.youtube.com/watch?v=r5R8gSgedh4 - Kid’s songs sung by Rock stars (although calling Nickelback “rock” is being fairly liberal with the term).

And the second is the best cover on the internet, no not Boyce Avenue or one of those crowds. It’s some 2 year old child singing Radiohead’s Weird Fishes. The album that was #1 in our 2007 Best Of list has been made all the more interesting:

Allegedly the world’s greatest music collection is on sale. Here, on eBay. Any donations to help me buy it would be fantastic:
