Sweet space tunes. I'm up to the 17 minute mark and it is heavily drawing from Yack's Senko No Ronde soundtracks. The first track named 'Y2024' sounds like a slightly modified version of 'Calm' (the music that played during waiting periods in online matches).
After the first 20 minutes or so it starts to sound more distinguished from Yack's tracks. My favorite track is at 'For the Record B' at the 42 minute mark.
The Official soundtrack cd release bundled with the artbook will be up for pre-order soon.
