Can You Recommend an Efficient Windows Based Music Player?

I love iTunes on my Mac but it is a real resource hog on my Windows system.

Before I ever started using iTunes, I used to really like Winamp which was a very efficient (not very resource intensive) music player. I tried Ogg Vorbis for a while a few years ago as well.

Now, I am thinking about switching from iTunes to something more lightweight on my Windows system. Have you used Winamp or Ogg Vorbis recently? How do they compare in terms of resource usage? Is there something out there that is even leaner?
