At least while doing my dissertation I can listen to Live Ireland. I don't think my students would let me during class. Mind you there are some Celtic groups that some of them like such as the Cranberries.
Lois, As I am a teacher of teenagers (history mainly but used to work in online learning) your dissertation sounds interesting. I'm working part time at the moment to do a PhD looking at the history of education. Hope you are enjoying the site.
