I'm downloading Iggy's and Azealia's mixtapes right now. I've been quite busy during Kesha's hiatus. Ive been digging deeper into other pop girl's discrographies and downloading their unreleased/prefame material. I'm going give Meghan Trainor's first two albums a listen too. I sampled them last week and liked what I heard
I might even get into ATRLs bandwagon favs except Tove Lo because she's terrible and overrated.
This hiatus was kind of a blessing because if Kesha would've released during this period, I'd probably pay dust to all these other artists and whatnot and wouldn't have fully given them a try
Lana has got me through the most
She has a bigger discrography than Kesha with full unreleased albums and EPs
It was nice going through all of them the same way that I did when I first found Kesha's. She has so many unreleased gems like Prom Song, Driving In Cars With Boys, Go Go Dancer, Hollywood's Dead and etc.
Kerli has an amazing unreleased catalog as well. She could've released so many albums right now
Katy's is cute too. Long Shot, Girl Next Door (sold), Watch Me Walk Away, The Box, The Driveaway, Everybody's changing>>>>> anything released after OOTB
Nicki's mixtapes slays anything she's released lately as well
Probably after ARTPOP Act II 
Her version of Skyscraper also slays
Scar Tissue and Skyscraper should've stayed hers. I like Selena's and Demi's versions, but Kerli just blows it out of the water
