I doubt it's because you're easy to please. I've studied music practically my entire life. this album is that good. it really is. there's clear thought out intent for basically every sound on the album.
I hope I explain this in an understandable way but it's one of those albums where when I listen I have all these different little moments that occur in which I anticipate. the opening of Institutionalized when the beat starts in earnest (~11 seconds in), the chorus effect on the keys in the opening of These Walls (~40 seconds in), the way the horn sort of sounds like a wilting flower during the last verse of These Walls, the entrance of the horn in For Sale? and how somber it sounds (~43 seconds in).
I love this album man. I'll be fluffing it for ages, I can tell.
