Heard R.E.M.'s "Mr. Richards" (which struck me as a very uncharacteristic R.E.M. song) in a bar and kept hearing similarities to other songs. Occasionally there were bits reminiscent of "Champagne Supernova," but there was something else that kept nagging at me, and I couldn't think of it while the song was playing.
Came home and found the song, and immediately realized what it reminded me of so strongly: "Funeral" by Devin Townsend.
Listen for yourself. They're even in the same key.
