Apple Music Library: Reboot Possibility?

Recently, it seems, all my music on my iTunes App on my Windows 10, has transferred to Apple Music. This was because I was solving another problem regarding transferring photos from my iPhone to my desktop. A move I greatly regret.

Anyway, now that all my music is on Apple music, the music in iTunes is completely different, much to my great disappointment. I prefer the iTunes set up but am now forced to start from scratch if I want my iTunes library with my paylists, to be what it was initially before the song migration to Apple music.

So now I am dealing with Apple music. It is awful. So my question is: can start over with Apple music. There are problems playing the songs, there are duplicates, and myriad other problems. I would like to delete the app and then try and download it again. Wil I be able to fill it with my song library as seamlessly as before. Or, just thinking out loud, since the Apple music library just took the songs from my iTunes library, and now my iTunes library is not the same, Apple music will not be able to do what I want. Anyway, there must be a better way to deal with Apple music library that is as nimble as the iTunes library.
