Two things are worth being good at here, so there are two boards.
Longest streak
Fastest correct guess
Whatever you type is what a stranger sees. Nothing else about you is stored.
How the clip works. The audio really does start at one second and grow: the same
thirty-second preview is played from the top and stopped at the window you have earned,
so asking for more time genuinely uncovers more music rather than revealing a bar that
was already playing. Guess sooner and it scores higher.
Where it comes from. Clips are the official previews from Deezer’s own API,
fetched at play time and played from their servers — nothing is hosted or re-served
here. Every track in the pool was checked against that API before being included.
