So, my music artists are all messed up in my music library by artists. I really need to change them to how I like it instead of what people made them (i.e. THE DOORS and The Doors). I also have a problem with certain artists such as The Beatles and The Flaming Lips. Even though they Have the same artist name on my music library, they still end up as separate artists. What media management program can change music tags in artist en masse and how do I solve the problem with my multiple artists (The Beatles, The Flaming Lips)?
