Touch, Oops, Private Show and Beep Beep are the ones that get stuck in my head most often, with Your Love trailing (love the delicate sections!) and then NMSS and NEM and NLY... the album is just loaded like that.
Freak is the one I *still* can't remember no matter how hard I try. Every track save D&D is giving me a replay craving, I finish a track and find myself wanting to replay the previous one.
The biggest problem with D&D for me is that they just aren't behind it emotionally like the rest of the album. Don't get me wrong, they nail the vocals and it shows they can do harder stuff and sound sharp doing it... but I just want the warmth and openness/connection of the rest of the album. I've seen a decent amount of hype for it on Twitter though.
