Animals, History, Scotland and Ireland, Nature, Languages
Oh goodness... It's a bit mixed, actually. I mostly listen to traditional or traditional/contemporary Scottish and Irish music (go figure), but also a bit of Canadian and New England-ish stuff. Sometimes a little pop or soft rock, but that's only on occasion. I also like instrumental music (piano, cello, and harp are my favorites to hear) and a cappella.
