I would like to add writing credit to Antonio Vivaldi for Concierto Para Mandolina in C Major played in Love Potion No. 9, which is not listed in the soundtrack in the movie credits
Just click the Edit Page button on the bottom of the Soundtracks page. I recommend you select Correct/Delete so you can see how the existing tracks are formatted. Then when you're on the page with those tracks, find the drop-down to Add items, and add 1 item.
Based on what you listed above, it would look something like this:
"Concierto Para Mandolina in C Major" Written by [link=nm0006334]
If you have more info, like who performed it, you'll see other items with such info, and can imitate them.
