I'm running Ubuntu Lucid on my netbook, and I like listening to music while doing other stuff. Problem is: Rhythmbox is constantly consuming 7-9% of my CPU while it's playing. Now, 9% might not seem like much, but it's more than double the sum of all other processes, and it's a battery killer.

Now, I know that any music player will be active (not idle) while playing, and thus will consume more CPU power than idle processes. But I'd still like to know if there's a good music player for Ubuntu that's light on CPU.
