1 · Brief describe the song in plain language
A driving psytrance anthem about losing yourself on the dancefloor at sunrise. First-person, present tense, references to lights, kick drum, transcendence. Avoid clichés like "feel the beat".

[intro] the lights start low, the bass starts slow
another night, another holy show [verse 1] six in the morning, the sun's still pretending
kick drum carries what the night was sending
shoes off, eyes closed, the city's still bending
no one's here for an ending
just one more lift, one more descending
the room is breathing, the floor is mending [chorus] we let go, we let go, we let go
oh the morning, oh the morning
arms up, head down, no warning
we let go, we let go, we let go [verse 2] ... [bridge] ... [outro] ...
