Where can I (pay) to actually download music and keep it?

[Jim2020]

Want to download lots of new music to my Apple Watch (non-cellular) for when I’m running.
Are there any services left that allow you to actually download the music but then not restrict it if you cancel? I could sign up to Apple Music but I don’t want to be tied in for ever more just to listen to offline content!
Cheers guys

What’s wrong with iTunes seeing as you have an Apple watch?

If you buy from Amazon it's yours to keep.
