I'm mostly shocked at how I simply was uninformed that spotify was using my connection so. I know over the past few months I've had occasional and even sometimes frequent spikes of latency while gaming.

I'm often left confuddled at these spikes as I won't have anything open I would consider requires much bandwith. Also, even though I would have high latency, opening a browser and navigating through sites would work as smoothly as ever.

Now I know to look at spotify specifically and I would not be very surprised if my spikes of bad internet activity are a result of spotify leeching my upload.

While I think it makes sense for spotify to use p2p in their system, I would have thought there would have been an indication of it in the options with an option to disable such services.
