my music in i-tunes is no longer available in list form

Several years ago I downloaded and paid for songs from iTunes. Until recently they were all available to me as a list on my iPhone in the "music" app. Now the list itself has disappeared and after much effort I can locate single songs only.

How can I restore the listing on the "music" app on my iPhone? This is an iPhone 13 and the updated version is IOS 26.0. I have the same songs on my second iPhone - 7 SE with the same problem.
