Angel Haze. She hasn't released an album in a decade but she still comes out with singles every now and then. My favourite songs are "No Limits" and "Weight"

I also love Meg the Stallion's Tramazine album.

Notable mention: "4AM in Toronto" by Miloh Smith & Junia-T

Like a lot of male dominant professions, women often have a hard time gaining success in this industry. Whether that's because fewer female rappers exist or labels are just less willing to sign them, I don't know.
