as Citadel's stations are now streamed by StreamTheWorld the old servers run by Limelight Networks are likely be switched off. This is what apparently happend to WABC-AM now.
The new stream URL for WABC-AM is http://provisioning.streamtheworld.com/ ... camaac.pls
, but it might not play on the SoundBridge because StreamTheWorld are using a flavour of AACplus that is not supported by Roku's devices.
