You need a category that says
"Stuff your girlfriend made you listen to to prove you loved her"

If you could stand listening to a few tracks of the mushy stuff, you're in love. If you cracked early and switched to real rock (in my case - stuff like Molly Hatchet and Blackfoot in High School), then you weren't really in love. I never made it to the second song, hence I was never in love. Probably saved me a lot of money and heartache anyways.

You could add Hall & Oates, Supertramp, Bread, and Journey to that group as well.
