Isabel Pérez, whose website includes a nice collection of anyhthing you can imagine for the EFL class, has also a good collection of songs to be used in class. This page on her web includes a good list of songs, clicking on each title you will get a podcast , some exercise to be printed and used as hadouts with your classes and a Youtube video if available. I hope you like this choice.
I was also trying to start my own collection NIce English songs when I came accross her page on her site. Nothing to compare with.
