Unchecking 'part of a compilation' for multiple items in iTunes? In iTunes, under the Artists list (brought up by ctrl+b in Windows), I have an unwanted 'Compilations' artist. In it are several tracks where the part of a compilation  box is checked when one goes to the get info --&gt; info tab. I can go through individually and uncheck this, but when I select multiple items at the same time, this box doesn't appear in the info tab anymore.

Is there a quick way to uncheck this box for multiple items?
Yes.  Select all of the items and press cmd + I.  iTunes will ask you if you want to edit info for multiple items.  Select yes, then select the options tab.  There should be a dropdown menu on the right if the words "Part of a Conpilation."  Select yes, and then click apply, and you should be all set!
