I don't use it but ui probably. ads maybe. plenty of people have money and don't want the inconvenience of trying to get around it.

No ads on music, no ads on shorts (shorts are allowed to freely use copyrighted music unlike long form video), background playback, downloading music to your device. These all are big value ads for me.

For me, it just comes with Premium, and I buy Premium to support the creators I watch often without having to watch ads. I want them to get paid.

You get music discovery, radios, go to album, go to artist

You can play youtube videos (ad free) as music on any chromecast device including chromecast homes with the microphone turned off.

Also, when playing music you won't be hit with ads.

Your setup can move with you wherever you are, home, travel, in the vehicle. This can be helpful for engaging the audible sensors of small aliens sans screen.

Youtube without ads on every device, anywhere, is quite a different experience.

Heaven forbid someone pay for an online service they use and enjoy.
