Comment 4 for bug 1539068

Yeah, as discussed on standup, this was specifically designed that way by Design team. The rationale was as you suspected - there is no way for user to "create" music, so there is no sensible action we could link the card to (we could surely show a dummy card which doesn't accept user input - similar to the card we have in My Music/My Videos where there no media files are present).
So the only way to see concierge for music is to go to My Music via Manage Dash.
