As someone who ISN'T a bandwagoner and has been checking for Banks ever since Work and Before I Ever Met You dropped I feel like I am uniquely qualified to speak on the quality of her music.
I can easily say that everyone's approach to music in this thread pretty much singlehandedly dismisses their opinion and renders it a subjective one. You have to be able to look beyond "liking a song or not" to truly be able to judge music. What's worse than judging music based on your affinity to the songs is judging it based on someone else's alledged affinity to said songs (see Lemonade and To Pimp A Butterfly)
