Ariana Grande, Miley Cyrus & Lorde have long careers as popstars ahead of them.
Meghan Trainor's success right now reminds me a ton of Ke$ha with Animal, and I could see her fading in a couple of years. However, I could be wrong if she proves otherwise and matures with the next era. Ke$ha's problem has been not releasing fast enough, especially after a dud era. She gave people the opportunity to stop caring, which a new-ish popstar really shouldn't do.
DeruLOW album sales numbers have arrived and they are even more embrassing than we originally predicted. She really needs to stop releasing music and become a go-go boi in some gay bar in Atlanta.
Zedd gave GaGa the worst songs in her discography (plus they were all old reused tracks) so it is hard for me to look at him in a positive light. I like the song that Troye Sivan did with him though.
Come to think of it, didn't Madeon do the same thing to GaGa with Mary Jane Holland? I don't count Gypsy as completely his since RedOne co-wrote it and Venus was sampled too. She picked some lazy producers.
