Songs are so much more than gap-fill exercises for an end of class /end of week "fun" activity. Used with some thought they can generate extraordinary language learning. For authentic songs there is a huge amount of resources available online and now A.I. can help with song meanings and class adaptation.
You don't always need to use all of a song. I often download a video and then edit what I need using "Shotcut".
The resources below are related to my didactic concert offer for schools and are mostly aimed at adult learners of English. (I work in the Escuela Oficial de Idiomas in Santander). Most can be adapted for secondary learners of English. As I add more, I will try to include some for primary schools too.
