There have been a lot of announcements building up in anticipation of Record Store Day 2012 (set your calendars for April 21 this year) but the largest one of them all dropped today in the form of the official list of every Record Store Day release. And it is extensive.

Luckily, the RSD website has a pretty handy drop-down menu that makes the viewing process a whole lot easier, but there are a bunch of bands either dropping full-length albums, vinyl re-issues, collaborations, live albums, unreleased tracks, and an entire spectrum of collectible artwork and album covers to mark the occasion.

Some of the big names on the list are the Arcade Fire with a "Sprawl II" remix, Animal Collective's ambitious audio project Transverse Temporal Gyrus, the Flaming Lips' collaborations album The Flaming Lips and Heady Fwends with Bon Iver, Ke$ha and Neon Indian (to name a few), and Phish, Lou Reed, and Paul Simon album re-releases.

Recent Billboard cover stars fun. are going to be celebrating RSD by releasing a 3-song acoustic 10" record that includes their huge track "We Are Young" (featuring Janelle Monae) and performing an in-store show at Newbury Comics in Boston ahead of their sold out show at the House of Blues that night.

The list is so extensive that there's really something for everyone, a big coup for the fifth anniversary of the event. The list is divided into exclusive releases, limited run/regional releases, and "Record Store Day First" releases, and you can download a .pdf of everything from the site as well.
