I know there's a huge controversy and discussion around Spotify introducing a lossless option. Apart from all that, how realistic is it that something is still in the works?

I recently took the online test to determine whether or not my hi-fi setup (and ears) can even discern the difference between "high quality" and "lossless". Long story short, I can. It makes a huge difference. I've been a long-time Spotify premium subscriber and have hundreds of playlists and favorites as a result. I signed up for Tidal in the interim but don't enjoy the online playlist converters and paying two bills for music.

Tl;dr: How realistic is the hope of seeing Spotify Hi-Fi actually happen?
