My artbook showed up yesterday, been digesting all of the content here. I overplayed The Alien and Invisible Monster when they were released, so I've been skipping them in my playthroughs. Answering the Call and Transcending Time are both great, the longer songs will just take more time to fully grasp. This is very much NOT DT by the numbers (to me), feels really fresh and inspired.
Also if on the fence, get the artbook - the team (band and art team) did a great job on it. I don't have a CD player anywhere, so I've been listening via the BluRay - the visuals are pretty cool.
*Edit - Also, JM wins the 'Digging for a spark' behind the scenes. When you see, you'll know.
