Just one small suggestion.

My suggestion would be an "are you sure?" box when removing artists from bands/albums, I did nearly remove one by accident once. Even though it's quite rare that someone would ever remove an artist by accident (it could happen though, I know they could just readd it but the accident could result in an unwanted autoreport), I would quite like to see something that confirms with you that you want to remove the artist.

It was from this that I learned why those "are you sure" messages are important (I don't mean just here, I mean all over the internet and those video games we play), I always used to think they were just a nuisance.

I edit the site quite a bit and I've never been in a situation where such a warning would be helpful. Perhaps you should be more careful.
