omg let me do this! Should be relatively easy since I've listened to all of these albums multiple times BUT I'll quickly listen through them all again.
Also on an unrelated note, while I agree with the 4 girls chosen, it kinda makes me realise how different the pop landscape is now. For example, back when Gaga/Katy/Kesha... even Lana to an extent, were "new"/slaying they literally only had 1, maybe 2 albums out. Ari has 3, Selena and Demi have 5 (?) and Meghan just released her second although AATB still feels relatively recent. Just an observation. Either things move a lot quicker with the new pop girls or I'm just slow lol
