BRAT has come up with a great mashup - Easy Heaven (Just Like Heaven and Easy by The Commodores). Just a preview so far, but well worth checking out. (Thanks BRAT)
Update (11/25/08): The full song is now available.
Update (08/03/15): And now 7 years later, BRAT has uploaded a newly remastered version. Also added a cleaner MP3 and FLAC files to download. (Thanks @bratmix)
