iTunes broke for whatever reason and I cannot launch it. I have reinstalled etc... no luck (this is on my desktop)

I am now on the market for new mp3/music software.

The key feature I need is the management aspect tha iTunes has: When I download a new song to my PC and open it with iTunes, the song would automatically be copied to a specific folder(Artist Name\Album) and a reference to this new copy would be added to the iTunes library.

I am tried both Windows Media Player and Winamp and neither seem to do this... Does Tag and Rename? Any plug-ins for WMP or Winamp?

Thanks
