I am running spotify on Ubuntu 15.04 using the installation method given by equaint in this thread (I had the same problem as the person creating the thread):
Now when I am trying to play a certain song, spotify freezes and eventually crashes (the song is "Koop Island Blues" by Koop). I haven't tried any other of their songs. When playing other stuff it works perfectly.
This seems very weird to me so I thought I should report it.
