Well , Spaw - I think I'd want to grab "This Land Is Your Land" for the following reasons. First it celibrates the beauty of nature. Next it would remind the corporations exactly who is the real owners of this land { no one and everyone }. And certainly because the song has the gift of the sing along chorus. That's a power not to be underestimated.

"And on the other side it didn't say nothing - this land was made for you and me"
