Pre-screening songs in Songbird would be Great

Being able to stop or "pre-screen" songs from playing without removing them from your library. itunes does this by using a checkmarks column to the left of the playlist/library where you can uncheck songs. The same functionality (not necessarily the same feature, but i wouldn't mind) is needed.

Albeit I'm not too experienced with Songbird, so if this is already provided in some menu or add-on, I'm terribly sorry (I did look, though).
