Sure, I can answer your question :) Tes, I tried to use YouTube Music with Chrome since it supports PWA installation, but it wasn't a good experience, the browser get synced with my Google Account and I don't like it, also my keyboard keys to change volume and tracks didn't work (with the Spotify app they work), maybe now they work, I know that PWA support in Chromium was pushed and evolving a lot recently.

Maybe I should try other chromium-based browser just for that, but also don't feel to have logged in my Google Account in other browser (if YTM has a desktop native app will be similar haha but IDK), hope Firefox desktop at some point support PWA installations. And maybe I'm old, but for products that I interact all day (spotify, figma, slack) I just like native desktop apps detached from browsers, even if they are Electron apps which are essentially a webapp wrapper.

About the Overcast suggestion, I'm a Windows/Ubuntu/Android person, I guess Overcast isn't for me, but I'm willing to pay $10/year for a product like Google Podcasts, I will look for products soon.

Also, Google Podcasts is free and ad-free, I never even see a promoted podcasts or something like that. But than can be one reason why Google shut it down. Google Keep is similar, simple, free and ad-free, I love it, hope they don't shut it down!
