How to make Rhythmbox PLAY mp3 file upon doubleclick?

[negativ]

I have .mp3 extension associated with Rhythmbox, and Rhythmbox OPENS but it does not automatically start playing the file when I double-click it. How can I make it so that doubleclicking an .mp3 will cause Rhythmbox to autoplay, as in the manner of Winamp?

Actually it should open the song on double click. However, it seems that in "party mode" (F11) the song is put in the play queue instead of being play.
