Ke$ha will drop her fourth and fifth albums within that timeframe, and that's all that really matters.

eww no more EDM anymore please. It's okay for remixes but not for original radio edits.

Ke$ha slaying again, becoming a legend etc

original =/= radio edit

We'll have enough Beyoncé snippets to compile an album.

This. I'm sure there will be trends with popular music but nothing dominate.

I think we're seeing this trend in general though with fashion, etc. Everything seems to be a free for all these days, which is how it should be. People should be allowed to make the kind of music they like and dress how they like, etc.
