You might compress it to 3gp or something.
It will be great in any quality.
When I was working in the children's camp this summer, I tried to advertise Yuki's music, and I have seemingly succeeded quite a bit. Everyone I let listen to Kalafina enjoyed it, though didn't feel quite comfortable around the lyrics (Japanese is still treated as something uber-exotic). When every team (one of which I supervised as a guide... minna-san, I'm really sorry, but I've no idea how to render these terms properly... think of a scout organisation, but much less formal and more leisure-oriented - this is a children's camp) could send one girl for a beauty contest, the program included a stage performance NECESARRILY aided by the team's guide (I guess that also has something to do with pedagogics
), so we made a short duet performance of Ballad. Then there was another event, where every team had to prepare and stage a pre-themed costume scene. We came out as a set of chess and staged a kind of chess battle to Godsibb. In both cases people who talked with me about their impressions mentioned "very good music", all as one. And my team, I think they at least memorised the name "Yuki Kajiura".
Here in Minsk, most of my groupmates are not much into Yuki's music except one girl who likes her violin pieces very much. My friend likes her music, too, but mostly concrete works like Tsubasa and Madlax, and he doesn't like her latest works much, especially KnK
My mother likes a bit of Yuki's music and even has "Yokoku" (KnK5/6) in her phone, but she doesn't like most songs, as for some reason she doesn't like Japanese as a song language. My father doesn't like anything from her works.
That's about all.
