Eh, not so sure about that. If you’re used to owning your music, being able to listen to it anywhere regardless of whether you have network access or not, and you find the idea of songs being removed from your collection or replaced with different versions without notice and without your consent to be appalling and borderline theft, not to mention the big data abuses that are almost certainly going on behind the scenes, then you’re probably too old for Spotify. I sure am.
I will only buy uncompressed, non-DRM’d music that I own, and that cannot be taken away from me.
