Your listening history,
on ATProto.

Malachite imports your Last.fm scrobbles and Spotify plays into Teal — the open music layer for the AT Protocol.

Import your full scrobble history from a Last.fm CSV data export.

Import extended streaming history from Spotify's JSON data export.

Merge both sources together with smart deduplication to avoid double-counting plays.

Only import records not already in Teal — safe to re-run any time.

Find and remove duplicate records already in your Teal account.
