Palm program that plays Windows Media Player files?

I’ve been looking on the Palm websites, but they haven’t been very helpful. Does anyone know where I can get a free Palm Media Player(I don’t actually care about the name) that is compatible with WMP files? I’d kinda like to listen to my songs on my Palm instead of on my computer.

Since I couldn’t find one, I’m betting the codec costs money.
Since the codec costs money, perhaps no one can afford (legally) to give the player away?
