Latin music
From Memory Alpha, the free Star Trek reference
Latin was a style of Earth music that originated from the Latin culture.
Mariachi is a type of music with a uptempo Latin beat; whereas the Spanish guitar is more of a gentle Latin beat. In order to pass the time while en route to Risa in the type 15 shuttlepod Onizuka, Geordi La Forge requested to listen to some Latin music. (TNG: "The Mind's Eye")
The mambo is also a type of Latin dance music. Jean-Luc Picard requested such music while the USS Enterprise-E visited Ba'ku in 2375. (Star Trek: Insurrection)
