Not sure if this is a bug or a network hiccup, but its consistent on v0.84. I access music on my home NAS using Fireplay from my office computer. Almost 100% of the time a song will begin loading (grey bar begins to creep right) for 1 to 10 seconds and then jumps back to the beginning and starts again, at which point the song begins to play.
Never seen this behaviour. I stream my music to work with an upload speed of 750 kps. Sometimes the streaming takes a second or two to start but it never goes back to zero.
My guess is a network related problem.
