Deep Cut Atlas
Find the releases your favorite artists slipped out
The algorithm found the artist. Deep Cut Atlas finds the albums.
Most artists you follow have a back catalog far deeper than the handful of songs in your rotation - albums, EPs, and singles you never owned. Deep Cut Atlas maps that catalog against your Apple Music library and queues the ones worth a listen to a "To Check Out" playlist.

The whole catalog, minus what you already own
Deep Cut Atlas diffs your favorite artists' full catalog - albums, EPs, singles, and compilations - against the tracks already in your Apple Music library, then shows you what's missing. Not just this week's drops: the back catalog you never got around to.

One tap to keep, one tap to dismiss
Add a release straight to your "To Check Out" playlist, or mark it not interested. No maybes, no forgetting what you meant to listen to.

A real Apple Music playlist, not another app to check
Everything you queue lives in a normal "To Check Out" playlist, synced through your own Apple Music account, filterable by recording type when you're ready to actually listen.

Grab what you heard on a playlist or the radio
History keeps everything you've listened to across playlists and radio. Catch something good and queue its album to "To Check Out" right there.
How it works
Three steps, on your device
- 01
Connect your library
Grant read-only access to your Apple Music library and listening history, processed entirely on your device.
- 02
See what you're missing
Deep Cut Atlas digs through each artist's catalog and shows you only the releases you don't already own.
- 03
Queue it or skip it
Add the good ones to "To Check Out," dismiss the rest. It all runs on your own Apple Music library, no separate account.
