Slopstop
Browser extension for Firefox and Chrome
YouTube Music keeps serving up tracks by artists that do not exist, churned out in bulk by generative models. Slopstop watches the player, and when a blocked artist comes on it presses thumbs down and skips to the next track. You do not have to sit through it, and the recommendation algorithm gets the message.
About 8,900 known AI acts are covered out of the box, from two community-maintained lists that refresh in the background. You can add your own artists, songs, and title keywords on top.
Install
Slopstop is not in the browser stores yet. Until it is, you can load it manually in about a minute.
Firefox 142 or newer
- Download and unpack the extension.
- Open
about:debugging#/runtime/this-firefox - Choose Load Temporary Add-on and select
manifest.json
Firefox removes temporary add-ons when it closes, so this needs repeating each session until the signed version is out.
Chrome
- Download and unpack the extension.
- Open
chrome://extensionsand switch on Developer mode - Choose Load unpacked and select the folder
How the blocking works
Blocking on artist names is easy to get wrong, so the matching is deliberately conservative.
- An artist name is only checked against the artist. The player bar also shows the album and year, and matching against all of it means an act called "Angel" takes out anything from an album with "angel" in the title.
- Single-word names have to match exactly. Around a third of the database is one word, and some of those are ordinary English words like Angel, Iris, Raven and Nova. Without exact matching you lose Angel Olsen and Nova Twins along with the AI acts.
- Your own keywords still match anywhere in the title, since that is the point of a keyword.
Every block is written to the browser console with the term it matched and which list that term came from, so you can always see why something was skipped.
Privacy
Slopstop collects nothing. No analytics, no accounts, no telemetry, no servers of ours. Your blocklists stay on your own device. The only network requests download two public artist lists, and they carry no information about you or what you listen to.
Details are on the privacy policy page.
Problems
If something gets blocked that should not have been, or slips through when
it should not, send me the console line beginning [Slopstop]
and I can usually tell what happened from that alone.
