I think there are a lot of other factors in that case.

The biggest reason why it’s rare to see regular cars get to a million miles is because they don’t get driven as much. At the average of 14k miles per year it would take 71 years for someone to drive 1 million miles. Since it takes so long to get there, many non engine related issues start taking hold like rust and obsoletion.

Yes, honestly the fact that ‘youtube music’ is literally just a different frontend for YouTube drives me nuts, it goes both ways, the YouTube app for TV doesn’t have proper features either, it’s unclear if you are getting the music or video version and the most egregious of them all imo, on the TV app, you can’t freaking browse for a different song while music is playing, you have to stop the song to go to the search bar.
