I'm submitting a song for SLS22 consideration. I'm submitting "21 Guns" by Green Day.
Green Day's "Know Your Enemy" was noticeably absent from the recently unveiled SLS21. I didn't mind it, but I thought it was a little too "American Idiot" and I know these guys can do better. "21 Guns" is a great deal better.
Although I won't see it for a year, I hear this song is prominently featured in the critically lambasted Transformers: Revenge of the Fallen.
