My view on this very feminist piece is that Winehouse wasn’t anywhere near as influential or impactful to music and other musicians as Nirvana (which is the article’s main point of comparison). Many other musicians and singers have come and gone (both male and female) and are not held in anywhere near the same reverence as Cobain, and that’s simply because they had no lasting impact.
Kurt hid his addiction, while Amy bragged about not going to rehab. She was also a victim of tabloids, who stood by while she wrecked her life. The inculsion of Kurt Cobain into the narrative is completely superfluos, and only serves to bolster the author’s political views.
