Rules for writing song lyrics that sing well and land emotionally: concrete imagery over abstraction, hook repetition, verse/chorus/bridge structure, natural rhyme, and prosody against the beat.
Rules for making TikTok and Reels videos that hold attention: the first-second hook, native-feel pacing, pattern interrupts, text overlays, trend use, loopability, and caption discipline.
