Don't restart playback when starting a mix from the track currently playing

Feature description:

Current behaviour: if starting a radio or instant mix from the currently playing track, when the mix finishes loading, playback of the current track restarts.

Desired behaviour: the mix begins without interrupting the track currently playing

Problem solved:

Playback shouldn’t restart - I’m already listening to the track I want to listen to.

Brought benefits:

Less listening to the first few seconds of a track twice

Other application solutions:

Google play music used to do this I think?
