Is there a way to have itunes automatically add/change genre information on your library songs?

just like how it already does with album art can it choose what genre of music the songs/artists belong to based on a database or something?Is there a way to have itunes automatically add/change genre information on your library songs?A person has to classify the music; there is no way for a computer program to know how to classify it. Once it has been classified then that information is put into a number of databases (which don't always agree, since different people maintain different databases).Is there a way to have itunes automatically add/change genre information on your library songs?not that i know of but u can select multiple songs and change all of them at once if u want to...just click on the first song and hold shift and click on the last song in group and click edit info do it that way
