That severely shortens the list of classical music as well and eh, jazz without a beat? Apart from the real modern *coughcrapcough* jazz I can't think of much.
If you can't get past the beat, it must be hard to find music you can stand.
Then again, easy torture method for you. ;-) It's always nice to know your friends buttons. O:)
