So, if I have a playlist in Spotify to listen to on long hikes, I will find out that I can't play it when I get to the hike (unless I use Spotify all the time, or think about this crap in advance).
Thanks, I understand that I can jump through hoops to make it work.
But an MP3 works 100% of the time, every time, without any of that crap, or thinking; I copy the file to a memory file once, and that's it. No passwords, no accounts, no internet, no logging in.
Many bands I listen to have Bandcamp/SoundCloud accounts, which offer DRM-free audio downloads. I use that when it's an option - and it pays the artists orders of magnitude more than Spotify ever will.
If I have a CD from a local show, I will rip that.
Otherwise, I am not going to make my life more inconvenient for the sake of a major artist getting $0.000002 from my Spotify subscription. I'll pirate their work.
Yes, that is the premise of this line of conversation, that you're using a music service all the time.
(Also it might be able to check in even when you're not actively using it.)

The problem isn't lack of data service on ships. It's things stopping to work offline.
Do you know any single person who travels outside of 4G coverage?
Because the $5/$10 mo doesn't do much for you in a National or State Park in the US two hours away from a major city.
