I run the little snitch firewall application on OS X and noticed this literally the first time Spotify ran (tip, EVERYONE running on mac should use this app, it's incredibly interesting to have a window into exactly what every application on your system is connecting to).

It's almost laughable the amount of connections it attempts to make to outside clients.

Anyways, the solution for me is simply to block all outgoing traffic to spotify that isn't directly to its streaming servers. Problem solved, no more outside peers eating up my upstream bandwidth.
