XM/Sirius have (temporarily?) canceled two punk rock stations, Fungus 53 and Sirius Punk, and are redirecting listeners to a 24-hour station “dedicated to Australian hard rock act AC/DC.” We’ve been told by readers that this is a temporary promotion and happens all the time, to which we ask, wtf? XM/Sirius sometime cancels real programming channels to run paid-for promotions? Do you get a refund on those channels, or what? [Punknews.org] (Thanks to Craig!)
