[BUG] Spotify buttons don't work (undefined)

[thetomatoplanet]

Describe the bug Sometimes when I click any of the spotify control buttons, nothing changes but the log file prints an error. After it stopped working once, it won't work until I restart the server app.

To Reproduce Steps to reproduce the behavior: It usually happens if I click a button twice or more times within a short time (which I often do if I turn the volume down or skip a few songs). The error is always in this scheme: spotify:[3 digit number] undefined

Expected behavior Spotify playback controls
