D:I found workaround, "HotSpot Shield".But its full of ADs and other annoying stuff(Unless you have Adblock Plus).
They also seem to be cracking down on people signing in when not appearing to be from UK, find a UK proxy and set it in Spotify's preferences ("Edit>Preferences..."). Using an HTTPS proxy at the moment without and problems.
BTW: Some people say it has ADs inside it, I haven't seen/heard a single AD in Spotify.
Yeah i hear adds too. They were telling me to fill in my tax return.
