I have bought a good bit of music from Amazon's MP3 store and have noticed one small problem when doing this. Instead of the red "Explicit" tag that the iTunes-based songs have when you open them in iTunes, Amazon just adds (Explicit) to the song name and album name. This is beyond annoying (and technologically unadvanced) to me and I want to tag them myself like I can do videos with MetaX. However, I don't know any application that will do this. I think someone suggested MetaX on the boards somewhere, so I'm clueless on an audio counterpart. Any ideas or help?
