I think George Michael was out of the closet way before that! Anyway, speaking of "Last Christmas", there is a much cooler version of that song out there by the alt-rock band "Jimmy Eat World."
Here are some truly awful Christmas music that I didn't see already mentioned here:
Mannheim Steamroller - Christmasville (entire album). By and large, the Christmas music of Mannheim Steamroller is great but their last album was incredibly awful with no redeeming qualities. As such, you can find it in the bargain bins at Wal-Mart and give it as a cheap Christmas gift to an obscure relative you'll hardly ever run into again.
Trans-Siberian Orchesta - A lot of people love this band and pay big money to see their Christmas concerts but I just don't understand the appeal of this music. The lead vocalist sounds like Meatloaf crossed with Michael Bolton, backed with members of Spinal Tap.
Michael Buble. The Barry Manilow of the 21st Century. Need I say more.
Ditto.
Love Michael Buble though. Very hip swing band singer. Pop stuff not so much.
Michael Bolton! Gaaa- nothing like someone who sounds like they’re constipated and straining singing a Christmas song.
Michael Buble- Trying to sound like Sinatra is bad enough, but trying to sound like Sinatra doing Christmas makes me queasy. The droning, talking old bar lizard sound doesn’t work with Christmas.
