Wow, this band sucks...?

You arrive at an awesome rock show and you are ready to have some head banging, guitar shredding fun. The first few bands have rocked and its time for the headliner. The band comes out. They have seven guitarists, two drummers, a bist who looks like he's ready to kill and a singer who you've heard has a voice that rivals that of God himself. You are stoked. The crowd is fired up as the band begins playing. Turns out, all they're playing is very much non-rocking tunes from Disney's Mulan. You are pissed. Something must be thrown at them. What do you throw?
