WhatA decentralized, user-owned music tracking and identity platform built on open protocols (like atproto) that aggregates listening data across all streaming services and gives users true ownership of their music history.
SignalLast.fm's independence moment highlights that music listening data has been trapped inside corporate silos for nearly two decades — users care deeply about this data but have zero ownership or portability, and the incumbent has stagnated under neglectful corporate ownership.
Why NowThe atproto/Bluesky ecosystem is maturing, data portability regulations are expanding globally, and Last.fm's corporate transition creates a rare window where users are re-evaluating where their music identity lives.
MarketMusic enthusiasts who track listening habits across services; ~50M Last.fm registered users plus Spotify's 250M+ subscribers who want cross-platform tracking. Competitors: Last.fm (stagnant), Spotify Wrapped (locked-in), teal.fm and rocksky.app (tiny, early).
MoatNetwork effects from social music graph plus accumulated listening history data that becomes more valuable over time — users with 15+ years of scrobble data won't switch easily once migrated.
