Sufjan Stevens and Justin Bieber are two names that we'd hardly see together. But 'The Age of Adz' artist is making headlines by giving his own little review of the Bieb's recent track with R. Kelly, 'PYD.'

"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 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," Stevens wrote on his Tumblr site.

Stevens has been pretty vocal about today's pop stars and shared his thoughts about Miley Cyrus' '#GetItRight.'

"One particular line causes concern: "I been laying in this bed all night long. Miley, technically speaking, you've been LYING, not LAYING, an irregular verb form that should only be used when there's an object, i.e. 'I been laying my tired booty on this bed all night long'" he wrote last month.

No matter what we feel about these songs, Steven's dripping sarcasm in his posts is too entertaining to pass up.
