Tiktok sounds that go viral usually have something that people can post about.
"I think I like this little life" = aesthetically pleasing photos of doing activities
"Me and the devil" = post about something you struggle with
"Oh no, oh no, oh no no no no no" = post something funny about something that went wrong
"You're a parasite" = I'm hardly going to post a photo of my friend's crappy boyfriend
"'cause baby I'm a liar, I'm a witch, and you and I have unfinished business" = idek, a photo of my situationship? People who hate me? How would this work?
"but you got me like ooooh yeah" = I just wouldn't lol
Edit to clarify: I've heard all of Emma's songs maybe once, sorry if I misinterpreted any of them. I just went through 3 of her most recent posts on tiktok
