Apparently we've been missing out on a number of musical delights from Arsenio Hall's new show, so we're adding Arsenio to the pool from which we pick our favorite musical performances on TV each week. And he didn't let us down.

Prince performed three songs on Arsenio, two with 3RDEYEGIRL and one with the New Power Generation.

Kanye West and Big Sean showed up to help out Rick Ross with "Sanctified" from his latest, Mastermind. Ross doesn't even show up until 3:15.

The week's most-discussed performance came from Future Islands, who played "Seasons (Waiting on You)" on Letterman. Not even Dave was immune to frontman Samuel Herring's enthusiasm.

Bob Mould also stopped by Letterman, playing "See a Little Light," his classic track from 1989.

Drive-By Truckers released English Oceans this week, and performed "Shit Shots Count" on Conan.

Lea Michele sang "Cannonball" from her solo debut on the Tonight Show.
