The eternally fashionable Buddy Holly. The man just continues to be an icon, decades after his short career ended in tragedy. You’ll want to remember this song for future reference. It’s one of those deceptively simple tunes that you can trace so much back down to. You almost can’t even call it evolution, because people are still copying the same basic structure without having to add too much. Some pretty famous people have used the formula with near-plagiarism faithfulness. But why mess with a perfect thing? There’s a reason why sharks and crocodiles haven’t changed in hundreds of millions of years; they’re already perfect, and so it is with the two-minute pop song as envisioned by Buddy Holly.
