Youtube Vanced is a Youtube clone app that allows you to watch videos without ads and listen to audio with your screen turned off.
It's a very convenient app, since Youtube ads are becoming ever more intrusive too.
It also includes Youtube Music.
It looks like the original Youtube app.
You just need to download and install Vanced Manager app from official site down below, install MicroG plugin and Youtube Vanced.
And voila! No more annoying ads all over the place, and those people on the public transport no longer need to know what you're listening to.
