Smart playlist? Add all of your jazz artists to it or use the jazz genre tag. As for finding it in the list, having it under each artist would make the library even longer to scroll through, which seems like a waste of space and time. If you type "armstrong" into the search bar, it will automatically find all his solo work and also any duets, trios, quartets, and what have you.Its so hard to remember which artist to look under... If Apple made it possible to have multiple artist tags, these songs could be found under any of the 3 artists names! It would make my library so much more organized.
