I am actually a bit jealous that he got into SDOIT that easily. Glass Prison was the first song that got me into DT but it took a lot of time to digest SDOIT.
What I find interesting is that SDOIT actually seems to have quite some grooves or even quite a lot of catchy parts? Never thought about this. The last albums aren't very heavy on groove (doesn't need to be a bad thing) which I think could be a problem for the guy. At the same time he didn't like SFAM that much.
Anyway, the way he listens to the album does translate directly to myself. I can't keep myself from smiling, head-banging, getting goosebumps, mesmerizing etc. Such a journey of an album!
