Your music lives here.
Your love travels.

YouTube Music · browser beta

Your browser plays. Your heart follows.

Install in Chrome or Brave on your computer. No desktop companion required. You can then use LoveButton on your phone to favorite the music playing on that computer. Safari and native mobile playback capture are not supported in this beta.

1. Connect your channel.

   Choose Connect YouTube Music in LoveButton. Check the channel shown in Settings: this is where your hearts are saved, even if your playback tab uses a different account.

2. Install the extension.

   Open the Chrome Web Store link above in the Chrome or Brave profile where you play YouTube Music and install LoveButton. You can use your own browser profile. Open the browser’s Extensions menu and optionally pin LoveButton so it is easy to find.

3. Pair your browser.

   In Settings → YouTube Music, create a browser pairing code. Enter the one-use code in the extension, select the playback-sharing consent checkbox, then choose Connect and share. If the code expires, create another. Pairing another browser or profile replaces your previous browser connection; only one can share at a time.

4. Press play.

   Open music.youtube.com. LoveButton chooses your most recently active playing music tab and keeps your paused track when nothing is playing. Check that the extension shows Connected to LoveButton and the expected track, then open LoveButton to use the heart. Pause sharing or Disconnect from the extension whenever you want.

5. Choose what your heart does.

   YouTube Music hearts default to your connected YouTube channel. In Settings, choose Last.fm, Both or YouTube Music. Connecting Last.fm also enables scrobbling by default unless you opted out. Turn scrobbling off in Settings if another app already handles it; the choice persists across reconnects.

Set up your Linux connector.

These steps are for a Linux host with systemd and sudo access. Download an available build above before starting.

1. Verify the download

   Run the command for your architecture and compare its full output checksum with the SHA256 shown beside the download. Continue only when they match.

   sha256sum lovebutton-roon-linux-amd64
   # For ARM: sha256sum lovebutton-roon-linux-arm64

2. Give the connector its own account

   Run these once. Substitute arm64 in the binary filename for an ARM machine.

   sudo useradd --system --user-group --home-dir /var/lib/lovebutton-roon --shell /usr/sbin/nologin lovebutton-roon
   sudo install -m 0755 lovebutton-roon-linux-amd64 /usr/local/bin/lovebutton-roon
   sudo install -d -m 0700 -o lovebutton-roon -g lovebutton-roon /var/lib/lovebutton-roon

3. Pair with your LoveButton account

   Open LoveButton, connect Last.fm, then choose Settings → Create pairing code. On Linux, replace the example HTTPS address with the LoveButton origin you are using, without a trailing path. The second command prompts for your one-use code.

   sudo -u lovebutton-roon /usr/local/bin/lovebutton-roon -config-dir /var/lib/lovebutton-roon -bridge https://YOUR-LOVEBUTTON-ORIGIN config
   sudo -u lovebutton-roon /usr/local/bin/lovebutton-roon -config-dir /var/lib/lovebutton-roon pair

   Keep this state directory private. It holds the connector credentials; do not copy it to another running connector.

4. Install the systemd service

   Create /etc/systemd/system/lovebutton-roon.service with the contents below using sudoedit /etc/systemd/system/lovebutton-roon.service.

   Show the complete service file

   [Unit]
   Description=Lovebutton Roon connector
   Wants=network-online.target
   After=network-online.target
   
   [Service]
   Type=simple
   User=lovebutton-roon
   Group=lovebutton-roon
   StateDirectory=lovebutton-roon
   StateDirectoryMode=0700
   ExecStart=/usr/local/bin/lovebutton-roon -config-dir /var/lib/lovebutton-roon serve
   Restart=on-failure
   RestartSec=5
   TimeoutStopSec=20
   UMask=0077
   NoNewPrivileges=true
   PrivateTmp=true
   ProtectSystem=strict
   ProtectHome=true
   ProtectKernelTunables=true
   ProtectControlGroups=true
   RestrictAddressFamilies=AF_INET AF_INET6 AF_UNIX
   
   [Install]
   WantedBy=multi-user.target
   

   Then load and start the service:

   sudo systemctl daemon-reload
   sudo systemctl enable --now lovebutton-roon
   sudo systemctl status lovebutton-roon
   sudo journalctl -u lovebutton-roon -n 50 --no-pager

5. Authorize in Roon, then enable your zones

   Open Roon → Settings → Extensions and enable Lovebutton. You can do this in the Roon app on your Mac: the extension itself runs on Linux. Cloud pairing and this Roon authorization are separate steps.

   Return to LoveButton → Settings, find your connector, and enable the zones you want to share. Track metadata stays private until each zone is enabled. Switch between zones in Now using the source picker, arrow buttons, or a deliberate vertical swipe.

   Roon hearts love and unlove tracks on Last.fm. They do not change Roon favorites.
