Missing streams

I’ve been have issues recently where my streams have gone missing. I know for a fact that I listened to glum by Hayley Williams (the single version) over 100 times last year and it’s just completely removed its self from my streams. The same thing is happening with multiple songs (all of Hayley Williams’s individual releases off of Ego death at a Batchelor party, popular of the wicked soundtrack and lots of others) particularly ones that I had high streams of last year -it’s really strange
