Not really what I was looking for but thanks for the suggestion.

On every site I’ve checked it uses a random css tag so can’t block more than one.

I am in a similar boat. Since you have Tidal might want to look into Tidal-dl to “backup” the things you especially like in high quality.

Tidal is actually not too bad, and it pays artists more than other services (not a lot, just more) but I do expect it to go downhill/away eventually so I make a habit of downloading what I can and supporting the artist directly in other ways.

I would love a radarr/sonarr style app but for YouTube with sponsorblock built in.

edit: sorry I missed where you said desktop app

This is actually a good sign that Google is taking steps to fix their broken search engine. All it seems to deliver anymore as SEO-optimized crap “blogs” with affiliate links. Linking to Reddit without the user having to include “reddit” in the search is a sign they’re actually trying to deliver good results again.
