When a concert headliner plays a set that lasts an hour or less, some fans feel shortchanged. Others prefer live music to be "short and sweet." We debate on the length of concerts, with Jon Bream of the Minneapolis Star Tribune and Jaime Lowe, author of Digging for Dirt: The Life and Death of ODB.

Tell us: How long should headlining acts perform in concert? Ever felt shortchanged after a too-brief headlining set? Have you ever wished an artist would "wrap it up?" Leave a comment below.
