Purchasing Tracks I have currently via Apple Music

Hi I have about 15 playlists set up on Apple Music, consisting of a mix of purchased tracks from I Tunes and Apple Music downloaded. I'm keen to purchase all of the tracks now and cant find a easy way round it. One way i was considering was to cancel the Apple subscription and hoping the songs stay within the playlists (although greyed out and unplayable) so i can just purchase those songs from I Tunes?

Any advice or if anyone has a easier way to purchase the Apple tracks would be well received.
