Rank these people according to popularity as of now?

1D, Biebs, Katy Perry, Gaga, Miley Cyrus In my opinion 1. 1D (just released best song ever and this is us, easily the most popular thing in music right now) 2. Biebs 3. Katy Perry 4. Gaga 5. Miley * just curious :)). I'm not a fan of any of these guys. I just wanna see who's really popular as of now
