So after removing the categories that I disagree with (love for yourself is not the same emotion as romantic love for another person, songs about how you’re glad you broke up are clearly about the emotions that replaced romantic love, and songs about lust may be about someone you also romantically love, but love and lust are different emotions) I can conclude that love songs are, in fact, declining in popularity, but also still make up a large percentage of popular songs.
Revanced still works. If yours stopped working, download the latest patches and make an updated .apk.
