Hard to say... my older cat, Chester, when he was alive, loved Beethoven and Bach (and would roll over on the carpet blissfully). My younger cat, Arthur, prefers Wagner (and races around the house like a Valkyrie when he hears it!).

But both were quite attracted by my tape of the "Jingle Cats", and both kept trying to get inside my boom-box where they thought those singing cats must be!
