Last time we heard from Sufjan Stevens, it was with his open letter to Miley Cyrus, and today he’s shifted his attention to another young star who has been in the news a lot lately: Justin Bieber. On his Tumblr, Sufjan shared the Justin Bieber and R. Kelly collaboration, “PYD.” He included this note with the post:

Shout out to over-sexed teenagers. Shout out to sex abbreviations that sound like the word “puberty.” Shout out to animal euthanasia as sexual innuendo. Shout out to out to the new genre: nymphomaniac pop. Shout out to my Biebs. Go get some, bro. I’ll be reading the psalms, eating Scotch oatmeal cookies, etc. The world is abundant.
