Pure coincidence to be honest. I was listening to game soundtracks on youtube and searched for "jin's theme"(what I wanted to listen was actually the theme of Tekken's Jin Kazama). However, out of curiosity I clicked on the first video that appeared and that was Lust SIN. I happened to like this track and tried to find out more about Blazblue and ended up ordering Calamity Trigger, since it was released in Europe just a few weeks ago.
