i don't know. i've been listening to trance, especially uplifting trance, for a few years now.. and it seems to be the same, again and again.
to use other words, i have no idea :|
well i listen to electronic music since the 80's in that time wasn't called trance was called only electronic music and i never tired. In that time there was a big competition between the rock music and electronic, it was almost forbidden people listen to electronic music, people used to say it was crap, rock was the music etc.
But it was always my favorite genre since that times, and in that time tecno was more popular than now and acid too.
