The hot new trend in metadata? Going all lowercase. The no-caps titles of “bad guy” and “thank u, next” emphasize that these songs work because they’re lighter than air, fizzy concoctions underplayed just the right amount by Billie and Ari. BROCKHAMPTON prefers all-caps presentation, and they are showier, but still smart enough not to smother their team chemistry with overbearing production. Even the latest Latin Pop boom is a subtler genre mash than Ricky Martin’s heyday - “Señorita” gets loads of mileage from a bare hint of Spanish guitar.
