The music mood is mostly fairly consistent from beginning to end. That would be ok if the songs are short and compact but once you start getting past the 3 minute mark. I would like to hear some sort of emotional climax, some build up in the piece
Regarding the compactness. For groove based music Steely Dan relatively have more ideas than most as the verse and chorus are noticeably different from each other but Steely Dan music is still groove based. Which means what propels the backing music of the song of each section isn't interesting harmonies/chord progressions but the groove itself. Not really my type of thing.
Regarding the 3-5 minute length. Yes it's normal length for pop songs but like I mention before bob Dylan ruin pop music by expanding the pop song length from a 2-3 minutes to 3-5 minutes. It's not 60's rock compactness
Regarding the instrumental parts. I'm sure they are meticulously composed and it's enjoyable to listen to. I'm just not wowed and blown away by the jazz soloing no matter if it was improvised or composed. Instrumental solo works in pop music as the emotional climax of the piece, the soloes here just seems like just another section of the song
