I can confirm this bug, including roughly the same percentage. (top indicates 20% process use, on an Intel X60 with Core 2 Duo)
The process goes to 0% CPU when "Stop playing song".
Sometimes, it uses a very reasonable 1..2% CPU.
The excessive CPU use has also been seen when a song is paused.
I can not reproduce the problem at the same severity when the playlist contains only a few songs. So there may be a relation with my bug https://bugs.launchpad.net/ubuntu/+source/amarok/+bug/474059
