Just found this site which is full of resources http://www.saberingles.com.ar/. Not the prettiest of sites, not the easiest to navigate and it comes with lots of ads BUT it does have a lot to offer. Check out for example the link on the left to Canciones. A great collection of lyrics in English and Spanish and if you scroll down and follow the “Ejercicios de comprensión” you will find even more. As I say, not the most beautiful but more than worth spending half an hour exploring.
