This is WAY FAR from Brazilian samba, it's something more to a jazzy, big band salsa that is played at the Caribbean clubs but damn this is a great upbeat remix! Keep up the good work! =)
Yeah, I've read about the naming mistranslation and your friend is correct saying it should be "Samba dos Anjos" but it's also incorrect in Spanish where it should be "Samba de los Angeles".
Best regards!
