This month, Cameron Crowe's 'We Bought a Zoo' hits theaters. Normally that would make for an anti-climactic No. 1 entry on a Best Soundtracks of 2011 list. After all, every single Crowe film -- yeah, even 'Elizabethtown' -- is set to an unbelievably rocking set of songs, which more or less double as a mixtape made from Crowe's personal music collection. (That's what you get from a director who used to write for Rolling Stone.) Alas, this year, Crowe's 'Zoo' is not No. 1 (it's actually No. 7). So who ended up nabbing the top spot? Find out below in Moviefone's Best Soundtracks of 2011.
