Where abouts do you live at the moment?Have you visited the uni?
I have a friend who graduated there last year in music, I'll try and get hold of her to get more info. I applied there a few years ago but wanted more emphasis on jazz and film muisc, which was offered in Notts (so I went there instead. No reflection on Queens itself, just the detail of the course). They've recently done up the building really well and have a nice performance space. I know lots of people who went there for other courses and Belfast is really becoming a cool city (at last!!!!

)
Let me know a bit more info and I'll see what I can find out for you.
