I couldn't name you one Beatles song off top, but I'll be the first to listen to people familiar with their work about their history and it's obvious how much of an impact they've had on the world both culturally and musically.
I think it's a bit myopic to just say fukk the Beatles without really knowing anything about them. Lord Jamar is entitled to his opinion but I bet he and many people in this thread are in the minority .
Black artists around that time and their financial status and the popularity of the Beatles aren't mutually exclusive.
