Pitchfork Media just released their Top 50 albums of 2009 and Top 100 tracks of 2009 with Animal Collective claiming number one on both lists with their eighth studio album Merriweather Post Pavilion and key track off of Merriweather, "My Girls".
I like Animal Collective and respect them as musicians but I honestly don't see what the fuss is about. "My Girls" is great and definitely deserves to be on the list (don't know about number one though,) but the album as a whole was just "eh" for me. It could also be because I attended a school where Animal Collective was what everyone was listening to and believed that music as we know it would change because of them so when it didn't exactly live up to the hype I expected, it turned me off maybe even more than it usually would. But it's no surprise Pitchfork gave them the number one spot for both, they've been raving about Merriweather Post Pavilion since it released in January 2009 giving the album overall a 9.6 in their review.
On a side note, Pitchfork is a great website to look for new music. They cover a lot of bands that aren't usually covered and you could even listen to them on the website thanks to their LALA player on the top right.
