I'm setting up a fresh iTunes library, and I'd like to have a playlist with some internet radio stations. However, I'm seeing inconsistent behavior with how these are being handled in iTunes 10. When I add The Current MP3 stream to a playlist, it does not show up in my main music list, however, when I add the BBC Radio 6 it does show up in the music list, not matter how I add it (dragging from the radio list directly, or adding the URL via Advanced > Open Stream).
Why are these streams treated differently? How can I prevent the BBC stream from showing up in the main music list (like The Current stream currently does)?
I'm using iTunes 10.5.2 (11) 64-bit on Lion
