I suddenly realized I don't have any authentic Merengue, Salsa, Bachata, Cumbia songs in my repertoire. Merengues were easy when all you had to play was Cuando, Cuando, Cuando, etc along with a lot of improvising, but I'd like to do the real thing.

I speak conversational Spanish and so I do the commercial songs (singing the Spanish words)...La Bamba, Guantanamera, Celito Lindo, etc.

What are you doing for the above genres? And does anyone know if there are Latin standards for the above that Spanish people always relate to (like we would consider Let Me Call You Sweetheart as a standard)?
