I have had this problem for more than a year now. Gapless playback on albums does not work on my desktop version.
For most albums this is a non issue since there are gaps there in the recording anyway.
But there are many albums, such as live concerts and some classical music recordings for example, in which the 1–3 second gap between tracks creates a silence or truncates the end of the track when there should be a seamless continuation from one track to the other.
This is quite annoying and something I wouldn't expect from Spotify.
Anyone who can answer why this is happening in my Spotify player?
