Consider this statement from his wife this week:

His music tastes tend toward Beethoven and Bruce Springsteen but "I force him to listen to Scarlatti and Bach," Mrs. Alito said in a Washington Post interview published Monday. He once attended a ska festival--that's rock music, with a touch of reggae and horns.

Hmmmm. Springsteen seems obvious (especially with a mother named Rose Alito). But, a middle-aged, New Jersey, Italian-American, Republican--and his wife doesn't identify Frank Sinatra among his musical favorites? Sounds like he's not being very forthcoming here...
