Heh, I remember you mentioning a while back you were dipping your toes into GU, and I've been meaning to ask: how are things going with that?
Limited time for gaming has meant limited time for talking about any soundtracks, but I'm planning at last to do a small feature on Sunbreak sometime soon. Actually, at this point there's nothing stopping from doing some kind of feature on it now, but I think for the moment I'd like to wait for an official release of the tracks in the later updates, which will probably happen sometime after the final update releases. Whether or not I even feature any of those tracks is undecided, but I'd like to at least have the full collection available to me before I start anything, seeing as it's probably not far off now.
Also, surprised to hear you say that the new tracks in Generations Ultimate didn't leave much of an impression on you. The expansion didn't add much music, but Silver Winged Star (Valfalk/Valstrax) is usually pretty popular.
And as always, if you ever need help tracking down the origin for something, feel free to ask me, as my knowledge is generally broad enough to pinpoint where stuff debuted.
