Newest Revision

I'm trying to figure out if I'm missing something in the newest release. Comments Please! In the last release before this and previous to that as well, I could select a album then dbl click on a track and it would play, no interaction with the play list, now it appears that dbl clicking results in adding the selected track to the playlist. While that maybe ok, how do I just play a single track ?? I do alot of just selecting things on the fly one at a time, and I no longer see a way to play without adding to a playlist
