Thanks,
This helped me revert to 11.0 from 11.0.4; when I upgraded to 11.0.4 it corrupted the driver/registry settings for my DVD drive and I couldn't rip any music. Microsoft FixIt tools could not fix the driver issue; downgrading iTunes was the only available fix.
Since version 11 I've been missing the art preview, but got over it when I discovered I could bring it up by clicking on the small artwork with the controls.
But I still hate the fact that I can't search the library for artists by "song artist" instead of "album artist", for songs on Various Artists compilations or soundtracks. Seems that my only solution is to go to the "Songs" view and sort them all by the Artist heading.
