I really like the other 2 voicings but I'm not 100% sure of my choice of voicing it as Cmin with Ab bass (to make a Abmaj7) I was wondering to what degree would context have to change for those 3 to be usable or the most optimal for specific contextual situations in your opinion? Is my choice the most appropriate for a Rickroll reharm/voicing?
i think in the rickroll song you'll need that dreamy C note under there and the Bb would be optional in terms of shine but most likely i think it would be Abmaj7. i'd bet on that being what they used. specifically i'd venture to wager that there is a good chance the G note was only in the vocal. (this is pending transpositions of course)
