Fun Fact:Kesha's debut album "Animal" dethroned "21" from the #1 spot on the Billboard Hot 100 and was the first and only album to do so, as well as being the first #1 album of this decade and "TiK ToK" was the first #1 single of this decade.
So, yes, Kesha will end Adele in 2016. History tends to repeat itself. Try not to get raped this time, though, K-Rose.
They play nice to those above them while purposefully destabilizing and making feel insecure those below or at their level so that they will appear better in comparison and then rise in position, then do the same to their former superiors. Extremely disruptive for any organization and often hard to detect.
