Radiohead - Pyramid Song
Beach Boys - God Only Knows (hey, shaddup!)
Sigur Rós - Viğrar Vel Til Loftàràsa, with English lyrics
Tool - Pushit version from Salival
Beatles - In My Life, Dear Prudence
Obligatory SY song - today it would be Wildflower Soul
And not only do I wish I could have written it, I wish I could play Kaki King's "Close your eyes and you'll burst into flames".
Check it if you've never heard of her:
