This is the "Cancionero Rumbero", put together by 'Barry Cox', the N.Y.C. based singer and web master of the Cuban Rumba blog: esquinarumbera.blogspot.com
These are the lyrics meticulously translated into Spanish from 175 of the most historically important songs within the Afro-Cuban 'Guaguancó', 'Rumba Columbia', Yambú and Abakúa music of Cuba.
Before this, there did not exist "in this detailed form" anything like it.
