Has anyone ever thought of making a player for ASF files? Because usually FIFA games and some other EA games have good soundtracks in ASF format and why isn't there a player for it? I was wondering what if someone can alos make a Winamp plugin for it?

These aren't 'EAC Files' they are Vivo files. *.ASF format is one of it's formats and you can play it through there. Download a Vivo editor or whatever.
