please be reasonable with your ranking and it can be based on anything tbh (just don't make it super obviously biased like 'omg demi ***** on bey and taylor'
Legend Tier:
Beyonce
Adele
A+: Main
Taylor
Rihanna
Gaga
Katy
P!nk
Miley
B: About to be Main tier
Ariana
C: 
Meghan
Selena
D: 
Demi
okay, reason:
Bey and Adele no question: Bey because she's literally over the popgirl route now (she acts like an indie artist now that just sells out stadiums). Adele because she's the British M.J. with 21 and now best selling album of the decade 25.
Taylor and Rih have been consistent from time to time bringing in commercial success and staying in the eye of the public. Gaga has been freefalling like its nothing but her TFM/BTW era is still a huge deal so she's up there, dare I say aligned with Katy.
P!nk has her 2013 era going for her but I think she's below the others just because she doesn't feel 'there' yet. I mean her acrobatics and all make her alone one of the most talented popgirls but one more era... JUST ONE MORE!
Miley is clearly the one that just broke out of the B-list after the Bangerz era.
Ari's ME era is one of the biggest pop era's of the decade clearly. And that's enough to put her in probation or nomination for Main status. If only Focus was a tad bit better she would be skyrocketing to the A+ tier now 3 #1's on her belt back-to-back with Focus, DW and Into You....
Meghan's been proving herself this time around but her music isn't the tea definitely (my opinion) and NO has been a perfect high peak fast fall hit that she has to revive herself somewhere down the line with a huge hit. And I still can't see her being a main global popgirl tbh. Selena's clearly below her because she has yet to achieve that one thing Meghan has:
selling albums and singles simulataneously.
Demi because she's Demi. she tries.....
and tries....
