I like to have some sort of theme for my classes and was suffering with a new program. My friend gave me an idea, since we are not native english speakers here, to NOT to use english at all.
A BIG nono, but such a great site http://top40-charts.com gives you the top 40 music from various countries. I had the class guessing what is the language of each song, etc. Some really nice songs too, that you may find from there. I made my class a mostly climbing class and a hard one, but with completely new music it was great! You will also be surprised to notice, how much same stuff goes areound the world....So be unique and go international!
