Chris, are you sure bug #694860 is a duplicate? As mentioned by Sebastien there, that one has roots in a spec [1] (”A compliant player should also keep playing if you close its window while it is playing”) whereas this one is just incorrect behavior (selecting ’Quit’ doesn’t actually quit). FWIF, I don’t agree with the spec and agree with Michael above: RB as all music players should just behave like other apps do without exceptions or special addons.

(It seems that the Finnish locale now also has ’Quit’ translated to mean quit and not ’Close’ as it was when I commented above.)
