I am having a little difficulty understanding what you want to do. It seems to me that you want to add the composer to all the tracks - whatever the cd - of the same song. Here's how I do that:

1. Under Query click advanced search
2. Click the tracks tab on the advanced search entry box
3. Choose track title from the Field pulldown
4. Choose contains from the condition pull-down
5. Type the key word(s) in the value box (say "jeep")
6. Add to list
7. Search

I get a list that has a number of columns that can be changed by right clicking on a column head (your choices then become the default). Left clicking on a column head sorts by that column. I can then highlight all the titles I want (shift or control clicking), say Jeep's Blues, then right click and choose properties and then enter "Duke Ellington - Johnny Hodges".

What do you want to do that this doesn't cover?
