Radio stations originating from female-fronted artists have 90% female artists featured. While I love my female-fronted bands, it's rather limiting/pigeon-holing to have a Sleater-Kinney radio only have female bands, even in unrelated genres. Another example, Grimes radio won't play awesome intricate electronic/dance music, but instead kind of similar sounding female vocalists (Angel Olsen, Warpaint, etc.) While I enjoy these female musicians, they certainly aren't of a similar genre to Grimes and would be more approriate if I'd selected a similar genre musician.
Any way that we could stop grouping female artists in radio just because they are female?
Spotify doesn't make any distinction between gender but I completely understand where you're coming from and rest assured, I've passed on your feedback on this. Let me know if there's anything else I can help you with.
