Great thread! Here's the whole of Tears For Fears' cult album "Songs From The Big Chair" covered by Brothertiger - and it's absolutely fantastic! I think this whole album is my favorite cover version :D
my favorite cover is either wonderland by natalia kills covered by nick epic (not on spotify), beat it by michael jackson coverd by fall out boy, or bohemian rapsody by queen coverd by panic! at the disco!
