http://www.mediamonkey.com Great program for organizing/playing your favorite mp3's. You can play your songs through their own interface, or go to TOOLS-OPTIONS-PLAYER and have it play in Winamp (I recommend Winamp). Makes it much easier to edit tags! You can change them individually or do a mass change for all songs by a particular band. What I like the best is the sorting feature. It will scan your hard drive for songs first time using the program. Once this is completed you have various ways of viewing/playing your songs. I sort them by "artist" and it makes it much easier to find what I want to play. They have a gold edition available, but the regular version is free!
