Allow double-click in playlist to play song

[ffes]

I would love to be able to double click to play that song/stream in a playlist directly.

Now I need to right click the song, choose Selected Items and Add to queue. Then go to the Queue and "finally" play the song.

Some contexts. I have created a m3u playlist in Mopidy with the streams of my favourite radio stations (found at radio-browser.info). Every stream becomes one song in the playlist of infinite length. For me adding one song is enough but I can understand that you may want to add all the songs of the playlist to the queue and play the selected song.
