If you're not using it for syncing with an iPod, the market is flooded with free "alternatives". I say "alternatives" because using iTunes on windows is like shooting oneself in the foot with a rusty harpoon. Twice.
Try WinAMP, or my personal favourite Foobar2000 (Which has an iPod plugin here, which may or may not still work, and may or may not continue working into the future. It's apple, and they don't like not being in control, so YMMV).
I'd stress that if you're not using iTunes for iPod things, don't use it. It's nice software on OS X, but the windows port isn't.
