What? You opted for Spotify model when you sign up for the service. I am pretty sure you are still free to purchase the music or album in iTunes.

You’re even still free to just go buy the CD and rip it, as odd as it sounds.

What happens with your iTunes music if your apple account would get locked? Sadly the only option nowadays would be purchasing hard discs, and hope theres no protection on the disk as you are not allowed to break it

ITunes has been DRM free for over a decade?

Nothing, you can download all the music DRM free first. You do own what you bought, at least from iTunes you do.

This is deeply insightful.
