There’s nothing ‘instant’ about being able to craft good EDM, hiphop etc..
Sure, you can craft a sound that will fool most over 60 codgers, but you’ll get a blank stare from kids who actually LIKE it!
Kind of like how it’s hard to create GOOD jazz or rock with an arranger. Sure, you’ll fool a few kids that don’t listen to the real thing, but not anyone who loves good jazz or rock!
I agree that harmonic complexity may have taken a backwards step, but rhythmical complexity has bounded forwards, layered loops and rhythmical arpeggios have made for a very difficult sound to emulate if you really don’t know what you’re doing (probably from not having listened to enough for it to have become ingrained).
Let’s face it, this is all just the musical equivalent of ‘Damn kids, get off my lawn!’ 😂
The worst of it is, we’ve probably forgotten how musicians from our grandparents’ age said the exact thing about us! I can certainly remember how I felt about the worth of their criticism..! 🙄😂
