Straight up what made me switch to YouTube premium was a bit of a 2 pronged thing really
They started including Google Play Music with it, and then I got an unskippable 1 hour ad in front of a video that after I reloaded the page I got the same ad again.
Edit: I don’t have an issue paying for a service if the price is right. I got what I wanted for I price I’m willing to pay.
