iTunes stupidity aside, the Rock and Roll Hall of Fame is a fantastic museum. It's open from 10AM to 5:30PM; we got there at 11AM and, a forty-minute break from lunch aside, we rushed through the huge Springsteen exhibit and the gift shop in order to get out before closing. The small-in-space-but-packed-with-stuff memorabilia exhibit took us around three hours. If you're a fan of music, it's worth a short trip or stopover in Cleveland just for the museum. $22 to get in and not a rip-off in any way.
