This song is so catchy that it can be used for teenagers and adults. I have used it with my students (2º, 3º ESO) and they really liked it and were involved in the activity. After doing the worksheet, it was translated and we discussed what the singer wanted to transmit and how sweet or painful love can be. Pros and cons!!! Pre-intermediate and intermediate level. The song contains activities such as putting sentences in order, fill in the blanks and match.
