Over the past year or so, I''ve been getting recommendations of music compilations full of buzzword-ish titles (i.e. "relaxing coffee jazz music", "Kenny G greatest hits", "music for meditation/relaxing/sleep/work yadda yadda yadda zen") in my YouTube recommendations, most of them with stock image thumbnails and posted by extremely suspicious channels that often posts multiple instances of the same video with the exact same tracklist/song.
I find this weird, since I typically only listen to studio albums by artists on YouTube and never specifically searched for any of the buzzword above. Does anyone know what caused them to be popular/recommended all of a sudden?
