i dunno.. sigh. i don't remember many details. i just remember loving the song and how it was produced. that's really all i can tell you.. other than that, i'm just as informed as you, single-wise.
i'm not sure.. but i'd say that out of the songs we've heard, PYHOM and Best Behaviour are the best choices for singles. but that's just my opinion.. i don't know.
i personally don't think all is well will be the single, but i could certainly be wrong. i don't think i'd want it to be one though. it's not.. i don't know. i can't explain it. it's my favorite new song, but i don't think it should be a single.
