Refrain

Discord Rich Presence for Apple Music on Linux.

Refrain shows what you're listening to on Apple Music as your Discord status — whether the audio is playing in a browser tab on music.apple.com or streaming from your phone over Bluetooth.

What it does

• Reads playback metadata from MPRIS — the standard way a Linux program says what it is playing — for Apple Music in any major browser, and over Bluetooth from any device that reports its track (AVRCP). Firefox and its relatives report the page they play; Chromium-based browsers need KDE's Plasma Browser Integration, which works outside KDE too — see troubleshooting.
• Forwards track + cover art to Discord via the local IPC socket.
• Optionally scrobbles to Last.fm alongside Discord (opt-in, with a crash-safe offline queue).
• Lives in your system tray with Play/Pause/Next/Previous controls.
• Keeps a recently played list — cover, time, source — of the last 30 songs by default, on your machine only.
• Provides a settings window (PySide6) for everything users typically want to tweak — privacy mode, sources, autostart, Bluetooth device picker.

Requirements

• Linux with D-Bus
• Python ≥ 3.11
• Discord desktop client running (Refrain talks to its IPC socket)
• For Bluetooth: BlueZ with AVRCP enabled

Install

The AppImage needs FUSE 2, which current distros no longer install by default: libfuse2t64 on Debian and Ubuntu, fuse-libs on Fedora, libfuse2 on openSUSE, fuse2 on Arch. Without it, start the AppImage with --appimage-extract-and-run.

A Flatpak manifest exists under packaging/flatpak/ for users who want to build it themselves; a Flathub submission is on the roadmap but not currently active. Build files for the live channels live under packaging/. See packaging/README.md for build instructions. Which versions can still be downloaded, and why the others were taken down: docs/releases.md.

From PyPI

Current distros no longer let pip install into the system Python, so install with pipx. dbus-python and PyGObject come from your distro; --system-site-packages lets Refrain use them instead of compiling its own. On Debian and Ubuntu:

sudo apt update && sudo apt install pipx python3-dbus python3-gi libxcb-cursor0
pipx install --system-site-packages refrain
pipx ensurepath   # once, if ~/.local/bin isn't on your PATH yet
refrain --install-desktop

Commands for Fedora and openSUSE, the source build, where the files land and how to remove them again: docs/install.md.

Tested on

Ten distributions are tested before every release, from Arch to Debian 13, on Plasma, GNOME, XFCE, Cinnamon, LXQt, Budgie, MATE and the tiling window managers. docs/install.md names them, and docs/test-matrix.md has the per-row checks and the distros that are out of scope.

First-time setup

Refrain needs a Discord Application ID to push status updates. Each user registers their own (free, takes 30 seconds):

1. Open https://discord.com/developers/applications and click New Application.
2. Give it a name you're entitled to use — that name is what shows up under "Listening to ..." in your Discord status. You can also upload a square image as the application icon; with Look up the application's name on Discord switched on, Refrain puts it in the corner of the album cover, and uses it in place of a cover it hasn't got.
3. Copy the Application ID from the General Information page.
4. Launch Refrain → Settings → General → Application ID → paste, OK.
5. In Discord: Settings → Activity privacy → Share your detected activities with others. A fresh Discord install has this switch off, and with it off nobody sees your status — Refrain looks connected either way. The Discord desktop app is required; Discord in a browser can't receive a status.

The first time you launch Refrain without a configured ID, the welcome wizard pops up with the setup steps + a live diagnostics panel that probes your D-Bus session and Discord IPC socket so you know up front whether your environment can host the RPC at all.

After the wizard, the Status window says You're all set. Play a song and it shows up in Discord within a few seconds.

Last.fm scrobbling

Refrain can scrobble to Last.fm alongside the Discord status — a second, independent channel, never a replacement. It's opt-in and off by default. Register your own free API account, then fill in Settings → Last.fm. The shared secret and session token are stored in your OS keyring, never in config.toml.

Full walkthrough, the scrobble rules and troubleshooting: docs/lastfm.md.

Privacy

Refrain is local-first: no Refrain server, no account, no telemetry, and the author receives nothing. Two lookups are on by default and can be switched off — cover art at Apple and the update check at GitHub. Everything else only runs once you set it up: Discord needs an Application ID, Last.fm is opt-in. Data always goes directly to that provider, never through anything of ours.

Privacy → Off is the global kill switch (no Discord status, no scrobbling) while keeping the tray + controls running. The Recently played list never leaves your machine.

Every data flow, what is kept and for how long, and how to erase it — written to GDPR transparency expectations — is in PRIVACY.md.
