How can I *completely* wipe an MP3's metadata?

I'm using "beets" to organize my mp3s. One album I bought from Amazon as mp3s is incorrectly marked as NOT a compilation when indeed it IS a compilation. I organize my files differently based on whether or not an album is a compilation. No matter what I attempt to do to these mp3s, the changes I apply to the ID3 tags do not stick. For example: mp3info -d ../amazon_album/* # This WIPES the tags mp3info ../amazon_album/01-01 - Track 1.mp3 ../amazon_album/01-01 - Track 1.mp3 does not have an ID3 1.x tag. But then when I open the file in any media player, ALL of the information is still there! So then I tried: mp3info -a "LOL" ../amazon_album/* mp3info ../amazon_album/01-01 - Track 1.mp3 File: ../amazon_album/01-01 - Track 1.mp3 Title: Track: Artist: LOL Album: Year: Comment: Genre: Yet, in any media player, it still retains all of the original information. Because of this, I'm not able to change the album to a "Compilation" which means I can't organize it in Beets the way I want. I've confirmed that it's not a file permissions issue. Am I doing something wrong? Is there another way to accomplish this in Linux? Or is there a way I can "trick" beets into treating it as a compilation (so that it uses my compilation path)?
