This thread probably won't get much attention, but Elvis is one of my favorite songwriters, with a discography that I think ranks up there with just about anyone's both in terms of quality and scope. If you can name a genre, he's probably dabbled in it. Most recently he made a funk/R&B album with the Roots called Wise Up Ghost, and it's really good. If you've never listened to him before, I suggest This Year's Model and/or Brutal Youth as access points. They're not going to give you the full range of what he's capable of, but they're fairly accessible, straight-forward pop/rock records that clicked pretty fast for me personally.
