Hahaha! Glad you're wracking your head around one of my tracks that's awesome to hear! Thank you so much :D Yeah, when in major key it's great to go from the major to the minor subdominant. Add in the 6 and drop it an octave and you got that inversion of the IIm7b5! The bittersweet chord! I don't write many tracks in the major key but when I do I use that chord at least once. :D
Side Note (Side Note): 7 days to wait for everyone's score is going to be paaaaaaaiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiin
