What does this mean? It means I’m going with my first instinct: D♭ Lydian, mainly because it’s just, like, in my feelings. But you could also say it’s E♭ Mixolydian if you’re enamored with the strong beat chord, or go back to A♭ major too because of the melodies. Or, why not classify this one as multimodal?
Part two of this groove is what I hear as C# Phrygian with a unique form. I’m going to call the “Someone said” and “Biggie” refrains part of the larger chorus, which would mean that the verses and choruses all have different lengths!
