Cleaning music

How can i clean my music in my itunes,like i got 2000 songs all with the wrong artists and names.

is there any program that can do this for me

Not that i know of, You can do the artist one at a time usually by selecting all the songs my the artist then modifying it, this will change all the selected songs to that artist. You should be able to do it all within Itunes but manually i'm afraid.

You could try a program from this site (http://www.mymusictools.com/download/mp3-tag-editor/) to maybe make it all a bit easier.

How did your 2000 songs manage to get all the wrong info?
