Alternative rockers the Flaming Lips, never ones to shy away from psychedelia, are streaming a new song on their MySpace page which extols the virtues of the magic mushroom. Titled “Anything You Say Now I Believe You,” the Lips’ cut is featured in the new psilocybin-extolling documentary, Know Your Mushrooms. The soundtrack features three Lips compositions, including the reliably trippy “Anything You Say.”

“Now I know the way the sky gets blue,” sings Lips leader Wayne Coyne. Of course you do.
