Jacqui Naylor, Lisa Dillan, Janis Ian, Muse, Rita Lee, Jacintha, Zoe Fitz Gerald Carter, Joycelyn Scofield, Gabi Hartmann, Renee Dominique, Lady Blackbird, Karen Souza, Clare Teal, Jnae, Jane Morgan, Salena Jones. Some of these may only have one or two really good songs but I included them because they hit at least one song out of the park.... Like Rebecca Pidgeon, every song of hers can't be a Spanish Harlem. If you aren't sure why they were included give me their name and I will give you at least one song to look at.

Daves true story, Primrose path, Somi Masekela, Cheryl Ben tyne, Luba Mason Chritina Perri, Brenda Boykin, Anette Askvik, Imelda May, Amanda Martinez. The rest of 25.
