Waveform Scrubber
A night-drive music player over a blurred photo of a neon-lit street: a square cover card, the title "Afterglow Avenue" by Juno Vale, and a waveform of sixty rounded bars with the elapsed and remaining time under it, above rewind, play/pause and fast-forward buttons. Dragging across the waveform scrubs it: the bars under the finger swell and brighten like a loupe sliding along the track, the played bars fill with a peach-to-pink gradient, and a white bubble rides above the tallest bar with the time under the finger. Letting go snaps the playhead to the start of a bar, the play button morphs between play and pause, and while the track plays the bars sway and throb to the beat.
