If they'd stopped in '98 I never would have heard of them, so no they shouldn't have stopped.

Obviously, they still like what they're doing, and there are plenty of people who still like what they're doing and want them to KEEP doing it, so no they shouldn't have stopped. As long as they want to make music and as long as they have an audience they should keep going.

(And I like Leppard's new album)
