When you pick up a copy of Spin's July issue on newsstands, a special surprise awaits: A free CD with ten covers of Smashing Pumpkins classics, presented by MySpace and Spin. While the street date of the July issue is almost a month away, you can start listening to these stellar tracks via each band's MySpace Page. Stay tuned to SPIN.com as we unveil each track from the collection throughout the next month.

Las Vegas emo-punk darlings Panic! At the Disco, who have toured with the likes of the Dresden Dolls, the Hush Sound and OK Go, give us track eight, "Tonight, Tonight." "We played 'Tonight Tonight' during our first headlining tour, says guitarist Ryan Ross of emo-cabaret giants Panic! At the Disco. "Our live version is actually the one on the compilation. It's a great live song, and we hear Billy Corgan is a fan, which is quite a thrill."

Now Hear This: Listen to Panic! At The Disco’s cover of "Tonight Tonight" via the band's MySpace page.
