If I open a playlist in iTunes 9.2.1 and select any song and click the Play button, iTunes plays it and then the rest of the list; but what I'd like to do is hear that one song and stop and select another and play that one. Is there a simple "preference"-type of thing to enable a "single-play" mode?

I can only think of overworking the checkboxes in the playlist (constantly checking and unchecking them, with the help of a keyboard shortcut), or maybe making a large number of playlists with just one song in each list.

Further: It would be good to be able to burn several lists to a CD, so that groups of songs will play through but not play into the next group until "told" to do so with the CD-player remote,for example by my pressing the "Next" button.
