Start from a phrase short enough to repeat over two bars. Give the verse one concrete object, such as the radio handset, a notification, or the light above a subway platform. Let the second chorus turn the opening detail into a payoff.
The starter cues are instrumentals. The lyric drafts, BPM, and keys in source/SONGBOOK.md can be used to produce vocal versions. Print the lead vocal and instrumental separately if the video will include lip sync. Use your own recreated chimes and sounds.
