Bands that people say are shocked to know you listen to

Midnight Oil and Hunters and Collectors are the main ones. If anyone knew I liked REM they might be surprised too......
 
I like a lot of classical music, which generally makes people raise an eyebrow when I tell them.

If they also know I listen to metal, I either get two eyebrows raised, or just the one raised twice as high.

Oh, I also like half of what I've heard of Amiel, which is her two singles. I can (and have) listened to Lovesong over and over and over again for half an hour before I decide to move on. I think it's the only "pop" single I've ever bought. Her second single isn't much though.
