Thanks, yea I love that song and the entire album is pretty good. I just got their new album, Post Merriweather Pavilion, which is not too bad so far. I've only listened to some of it, and not in the right frame of mind yet, but I'll get to it eventually. The second album I mentioned (Panda Bear) is a solo album by one of the band members of Animal Collective so it's similar style but pretty different at the same time. I love listening to experimental music when under the influence, it helps to broaden your mind and open you up to new things.
Some of my other favorites:
The Skatalites (good for chill, happy music)
Pink Floyd- Dark Side of the Moon (never gets old)
The Slackers- Slack in Japan (good quality live show with chill music)
Slightly Stoopid- Closer to the Sun, or any of their albums
Bob Marley- Legend, how could I forget the greatest of the greats
Shwayze has some decent jams on his self-titled album, although I saw him live and was disappointed with the performance.
