iTunes plays when display closed?

[schafer]

I have a MackBookPro, 10.4.9

Recently, I closed the lid on my laptop while iTunes was playing -- it continued playing and I really liked the "new" feature.

I then went into preferences to automatically put computer to sleep and now whenever iTunes is playing, I close the lid and the music stops.

Question: Does iTunes continue playing when the display lid is closed?

Thanks.
