for some strange reason, it would seem either (a) no one else has this problem in the entire ubuntu world or (b) no one has thought of posting to resolve it; so, here goes:

i'm stuck behind a rather restrictive proxy at work; many, many sites are blocked. when i fire-up my lastfm player, make sure my authentication and proxy information is correct, my stream cannot connect. it can show me playlists and album information--including cover art--but no music at all. after it flips through a couple of covers, i get a pop-up message:
There was a problem contacting the radio streamer. Please try again later.
Http error: Server closed connection unexpectedly
losing my mind not being able to scrobble and listen... any help would greatly be appreciated!
