Personally I voted Adele,P!nk and Lana.
Adele for obvious reasons.
P!nk has always been vocala bout everything she does and progressed her childhood in her music.
And Lana barely changed at all.
She made alternative pop before - she does it now.
She dyed her hair but otherwise she didn't change much either.
Her lyrics still are about the same things.
Retro glamour,rich men,lolita stuff etc. have always been prominent in her music(Hundred Dollar Bill) and still is now.
Wel her name of course
