|Cupid cries over a bag of gold;|
a man pines over his tragic loss.
Perhaps there is some beauty in just listening to the music when you don't speak Spanish. But I am sure that you will be convinced by this post that knowing the lyrics of at least a few tangos can be very important, especially the lyrics for a song you might want to perform or use for a special occasion, such as a wedding.
Biagi's interpretation of "La Marcha Nupcial" (the Wedding March) is an excellent example! I know. I just was married, and the majority of guests were from the tango community. Sure, it was tempting to play "La Marcha Nupcial" at our milonga/reception after exiting a wedding palace in Strasbourg, France. However, this tango's lyrics would have created an ironic backdrop--once you know the meaning of the words (given in English below).
