When listening to Radiohab.com via Shoutcast with the current version (2.2.1) I experience short breaks after each song starts.
Phone connected via wifi, using default streaming engine. Each new song plays for about a second, then breaks for ~half a second, then continues to play.
The song title changes _after_ the song continues to play. My thought however was, that it might be related to the song title being transmitted since the problem only happens once for each song and right at the start.
EDIT: Doesn't happen for every song (start), but most. You'll probably need to listen for a few to reproduce it. Phone being used is Nexus S.
