Moving from Apple Music

Apple Music knows what you played. sleeves turns that into a diary without your history leaving your device.

In the Music app on a Mac, File, Library, Export Library saves Library.xml. Or ask privacy.apple.com for your Apple Media Services data, which includes Apple Music Play Activity.csv with every play.
Choose the file on sleeves' import page. It is read on your device and never uploaded: sleeves gets only the artist, album, suggested score, and date (if you want one) of each album you tick. It then shows you what it found on sleeves, and what it did not, before anything is logged.

What carries over

Every album you played more than a couple of times, with a suggested score from 3 to 5 that you can change before anything is logged.
When you first played it, as the month (the default), the exact day, or not at all. You choose.
Not play counts, single plays, tracks, or times. They never leave your device.

A diary of albums you chose to log, with scores and notes, not a record of every play.
Lists, a Top Four on your profile, and people to follow.
Critics' scores sit beside people's on every album.

The catalog comes from MusicBrainz. Very obscure or physical-only releases can be missing; you can add them to MusicBrainz and they show up here.
Genres are MusicBrainz tags rather than voted genres, and moods are a short list you vote on with a tap, not open descriptors.
Scores for single tracks. You can mark your favourite tracks on an album with a heart, and the most loved ones are charted.
