What I'm looking for is software that will let me change the title, artist, and album on an MP3. I've a collection of MP3s pulled from artists's sites, from CDs I own, from friends, etc., and many of them either don't have this information, or have incorrect information. I've got a player I like, but it uses the embedded info to allow sorts by artist and title. It really sucks when half the files come up with by artist "Unknown." Does anyone know of software that will let me change that embedded information?
