You strike me as a man with considerable musical integrity, so I think you owe yourself to give her a second chance.
Comparing her to Rebecca Black is just evidence of ignorance. Inga Copeland, Twigs and 18+, only more dada and outsider, that's the more proper associations.

(Granted, I may be at an unfair advantage here, as her name was completely unknown to me before this album popped up in 2012, I had no preconceptions)
