Audio Player UI

To be honest, I'm still not really satisfied with audio app UIs. I feel things are a little stale these days. So I thought about a couple of things:

- Why not integrate currently played song-titles into the tabbar?
- Why not have the now-playing-interface hide behind the content instead of it being above the content?
- How to get big album-artwork in front of people with phone-screens getting bigger and bigger?

I would love to hear your feedback on this!
