I second this. Probably the best $15 I spend for my family every month. No ads for kids watching YT on their own is nice peace of mind for me and my wife.
And because I already pay for it, we've slowly all migrated over from Spotify to YT Music and been surprisingly happy with it.
Believe it or not, they thought of that when they created start/stop systems.
In cars with these systems, the back pressure in the engine's cylinders is greatly reduced via a variety of strategies including selective alteration of valve timing and purpose-built secondary valves. What this means in effect is that the torque required to re-start the engine is a fraction of a dead cold start, and even a fraction of a normal warm start. This should serve to minimize additional destructive wear on components.
In effect, well-designed start-stop systems do not create any additional wear on vital engine components versus the engine running for that same period of time.
I've been pretty happy with Tusky
