One of the best songs of the year, Labios Compartidos is a great song and is very clear in it's context and visual aids!

Although my students will learn more than this throughout their Spanish language/culture career, this gives parents, peers, etc. an idea of what students will learn in a de-contextualized context. If you ever took Spanish, try to listen to it because many things parents and students alike will recognize, and of course it has great photos to go with it!
