Spotify employees seem to have no issue with songs about killing police, assaulting women, bashing gays etc. Just listen to a mainstream rapper like Eminem and there is plenty to get offended about, if they cared too.
A tame lyric for example:
“But I may fight for gay rights, especially if that dyke is more of a knockout than Janay Rice/Play nice? Bitch I’ll punch Lana Del Rey right in the face twice, like Ray Rice in broad daylight in the plain sight of the elevator surveillance/’Til her head is banging on the railing, then celebrate with the Ravens.”
