I've just changed computer and installed Spotify on the new one (Dell computer).
While I'm listening to my music, every track stops at a certain point (and the message that it's impossible to play the track pops up), and then resume playing, and then stops again, and so on till the end of the song.
Those are the same song I've listened till yesterday on the other computer without any kind of trouble.
I've uninstalled and reinstalled spotify but there's still the same problem.
We're closing this thread since the latest update seems to have fixed this issue.
Don't hesitate to open a new thread if anything else comes up.
All the best.
