How it works

1
Upload

Drop your Spotify export — parsed in your browser, never stored as a file.

2
We find your calls

Only artists who blew up count. We check when you first played them vs. when they took off.

3
Get scored & ranked

Earlier + bigger = higher. Grab a holo card and climb the board.

Your upload is parsed to per-artist first-play dates + a score — it never leaves as a file. Not affiliated with Spotify.
