So I've been organizing all my music on my PC before storing them on my mac for the sole reason that when Windows Media Player searched for the album info, it also adds the original artist and/or composer info. On most bands it's not a big deal, but for bands like the Beatles, Pink Floyd, Zeppelin, etc.. it's nice to know who composed what song.

Does anyone know a program that will download original artist or composer info on a mac? Or even a website that offers that information? Or if there's a way to tap into the mediaservices server that WMP uses to get that info? I hate being dependent on two computer just two organize my music (to as close to perfection as I can)
Thanks!
