Search for specific music in iTunes Store
Using my MacBook Pro, I wish to find music in iTunes Store that I can preview. Now I enter my search subject in the search bar at upper left and then hit iTunes Store. This will find my search subject in Music rather than the iTunes Store. When I try to preview the subject, I get the Apple Music ad and no preview.
Or I can open iTunes Store, but I see no way to search for a song in the iTunes Store, except as described above. For this reason, it has been quite a while since I have purchases any music on iTunes. This was a bad software decision.
