interesting, i don't think i'd ever heard of this project, but this could be useful if using winamp ever becomes untenable for me (or if i need something better for playing music on mac or linux than vlc, or if i get bored with winamp and just want to see what else is out there, since this appears to be actively maintained).

edit: and it says it lets you use winamp classic skins, which is a nice nostalgic touch.
