Yep, but I am talking about the official native library - libspotify. Even though it is quite outdated, it is a native Linux library directly from Spotify. Without it, there would be no CuteSpot, no Spotlight for Kodi, etc.

As I said, I have no problems with unofficial apps (quite the opposite - I usually prefer them to the official ones), but I don't see the point of trying to come up with a hack to have offline music for free, when for just a few €/$, you could instead support both artists and a company that has been quite friendly to both Linux community and 3rd party apps.

Yet at the same time, people throw money at any attempt to have a working Whatsapp client and until now (before it became free) had no problem with paying to the company, that is actively hostile to 3rd party apps. Oh well...
