I don’t know what airlines you fly, but I have never had a problem, especially while reading. I use a kindle app on my phone for reading on an airplane because it is easier to hold in close quarters.
You can actually use Spotify for music on a plane, as well, for your own music lists, after you download the songs.
It’s only during takeoff and landings. Also, It’s been about 8 months since I’ve been on a plane. It’s a good thing too, because I was inching closer and closer to saying something that would get me on the no-fly list. ;-)
