Overlay Notifications

An idea: maybe simply not handle music in the messages app at all, and we can have a separate overlay app to show music?

Could do... The messages app (and notify icon) was an easy way to get to music though... I don't know if people use it, but it seemed convenient

There're metrics hinting regarding this, namely installs and favourites of Messages Music in the app loader, 5 and 7 respectively when I view it now. How to interpret those I'm not sure though.
