It was as shame that Spotify could not play gapless from the very beginning. So I was relieved when I learned that it has been fixed, after 2 or so years of requests.
And still, several months later, I encounter albums which are not gapless.
I am paying for Spotify Premium, and it is very annoying that while paying full price, I still have to endure so many flaws of the sevice. There are albums with tracks greyed out, there are albums with tracks substituted by tracks by other performers (I call it a cheat by Spotify). And even the promised feature of gapless playback, a feature that decent players have had for years, sometimes does not work.
Here is an example of a terrible gaps between tracks. Try going from track 2 to 3, 9 to 10 (horrendous!), or 10 to 11. Unacceptable.
