Pop Lyric System

In pop, phonetic mass beats semantic precision.

Pop chorus craft is acoustic before it is semantic. A chorus that delivers phonetic mass — clean vowel-on-downbeat alignment, syllable-stress regularity, repeated hook centers — is singable on first listen by non-native speakers. Pop's 5-substyle system (dance-pop / confessional-pop / pop-R&B / alt-pop / anthem-pop) gates output through phonetic-shape declaration BEFORE chorus words exist.
