Feature: Play next in shuffle

[crispy-caesus]

Is your feature request related to a problem? Please describe.

When I'm in shuffle mode, I can't add any song to play next. Sometimes I want to listen to a specific song right in a shuffle session. I can turn off shuffle and add it wait for it to come on and turn on shuffle again, but that can be annoying.

Describe the solution you'd like

I'm not sure how shuffle works at the moment. If it's only determined when the next song is about to play, make it first check if there's a play next coming up. If shuffle is predetermined just move the play next in right after the next song in the shuffled queue.
