Premium is a great service for $4 a month and it's just handy to be able to use the real YouTube app when you need to. I personally use SmartTube on my Android TV and I absolutely love it.
I also use NewPipe x SponsorBlock on my phone if I want to listen to podcasts without any ad reads and it's occasionally handy if I want to listen to music on YouTube and not keep my screen on although I use Spotify for music most of the time.
PlexAmp is great for my MP3 collection which is all on a Plex server in the cloud along with all my movies and TV shows. UI is a little quirky but it has all sorts of cool features like AI powered suggestions that use GPT4 tech and lots of other cool stuff
Advertising spend has dried up and the shareholders are looking for growth. I don't mind paying for YouTube Premium but I get it much cheaper than that because I connect via VPN when I pay for it. I use Romania but other people recommend Turkey or Argentina or any of the other countries that are having issues with their currencies.
