I think music plays a vital role in teaching a language to students. Not only does it give more insight into a culture, but also sheds light on language structure (grammar) and vocabulary. And, of course, music can be pleasant to the ear, making us want to sing or dance along.
I have a French music playlist on Youtube:
I also love these playlists by French and Spanish language specialist Isabelle Jones.
Isabelle wrote a really good blog post about music in the language classroom here.
