Place it right after the donation banner appears, following a short pop so viewers register the alert before the music takes over, then let the clip finish the moment on its own.

This is a 12-second instrumental trap track, Esta Noche by Gonza YG, with no vocals, made to mark a moment on stream. It feels energetic and attention-grabbing, the kind of short burst that lifts the room as soon as a donation comes in. It is used as the Melox33 donation sound.
