By far one of the most popular songs in any of my Spanish classes is La llave de mi corazón, by Juan Luis Guerra. No wonder he won so many Latin Grammys last year!
Target features: Subjuctive for reason of influence, tiene, soy de/es de.
Video: Available on YouTube. High interest, upbeat, great!!
Questionable content: None, either in the lyrics or in the video. My favorite kind!
