Yes, it will all be ‘soundtrack’. Also, I can’t separate out ‘performer’ as someone other than the main composer of the film, even if the track in question is not by him/her. Otherwise, iTunes splits the album up in pieces. I view it by “albums”, and albums are all sorted by “album artist”. So that means that songs or tracks NOT by the composer on the album will also have the composer named (to use Nick’s example above, the Roy Orbison song will in my case be attributed to Ennio Morricone). It’s wrong, of course, but it keeps the neatness and tidiness of the way I use iTunes. I might, instead, denote the actual artist in the track name.
