You can now request songs to be in the game.  I've already put in a couple dozen lesser known metal/rock requests.

That has been there for a while.  Don't waste your time, it is irrelevant.  It's about as effective as  "liking and commenting" on things to save children in africa.  

I would imagine it has a little more effect than that.  But yeah, I'm not exactly optimistic about my preferred music being included.
