Regarding the Maj7#11 question, what about Billy Joel's New York State of Mind? I'm not sure if I'm misunderstanding something, but that song seems to feature it and I think it works... What say you?
just listened to the entire first verse and it's not there. just listened to the second verse and it's not there either. just listened to the entire bridge, it's not there. here's another verse, i doubt it will be here because all the verses are the same. seems it's not in the entire AABA,  ... the song is long so i'm skipping through these verses cuz they seem to be all the same ... another bridge, ... whole song seems to be just these 2 sections, .... anything maj7#11 is virtually nowhere. ah, the second to last chord of the song uses it, not in the verse/bridge etc but just to end it. yes, that is where it usually makes sense, on a b2 chord. actually my first draft of the ending of 'long long long journey' used it this way, right before the end. i can't remember if i said this before but the main place that chord normally seems to work is on b2 chords, which makes sense because the 1 and 5 notes of the key would be those 2 notes it is supposed to have. commonly used on guitar in the key of E, you'd hear F with the high E and B strings still ringing.
