All the Artist/Album tags on my MP3 collection are fine, but the Genres and Year tags are all horrendous.
For Genre, songs just seem to be all over the place. It classifies Iron Maiden is Alternative, Ozzy as Oldies, and Pink Floyd as Pop.
Year is even worse, because Amazon always seems to use the "remastered" year instead of the year the actual album came out. For example, it tags my Led Zeppelin albums as coming out in 1990+.
Is there any program that, assuming the artist and album is already correct, will automatically fix the Genre and Year tags?
