This would be great, exactly what I need. But they don't seem to offer it everywhere. I get the message "This offer is not available" when I go to https://www.youtube.com/premiumlite

I honestly would prefer a premium-lite. I don't use YT as an audio source so background tab audio is annoying (even more on mobile - stopping my phone doesn't stop the video). Really want premium-lite for family sub :D
