In modern music, "audio production" is arguably more important than any other aspect. If we judged your average top 10 hit by the same standards (melody, harmonization) that we did a Bach piece, no modern music would be considered "good" (le wrong generation, I get it). But these songs are popular and drive a multimillion dollar industry, so they must be doing something right. I would point straight to production quality and technique. Why is Dr. Dre so popular? He's a decent rapper but he doesn't really have much content volume. He's who he is because he's one of the best producers in hip-hop. He made a career, a legacy, and an industry out of just being really good at production.
