There's various options, depending on what you want to say. Since you only get one song you can't say it all but you might consider....
- Big Yellow Taxi - Joni Mitchell
- F*** You! - Cee Lo Jones
- We're Not Gonna Take It - Twisted Sister
- Put It There Pal - Richard Thompson (the live version from the DVD, so you get one last, stinking, stinging, pissed-off-as-can-be guitar solo)
- When The Music's Over - The Doors
- Everybody Knows - Leonard Cohen
And I'm sure there must be something in Joe's Garage that would send a suitable message
