They can't get everyone but the omission of Diana Ross (in the solo category) and Streisand is seriously undermining their credibility. You don't even have like theses two to understand their contributions to the music industry as a whole. Diana Ross for sure has pretty much influenced and paved the way for every popular singer both Black and White since the 70's (including some on their current list: Mariah Carey, Mary J. Blige, Sade). It's baffling.
