I does differentiate at some point, because during scanning, you can  
specify whether you want audio-only channels or not. This information  
shouldn't be dropped but saved in the channels table during the  
scanning process, so it could be reused later.
Another obvious use case would be to provide a different UI for radio  
channels, e.g. a visualization from mythmusic instead of a completely  
black screen.
