From here it works like it should both on the server side and the client sides I tested.

If you open http://somafm.com/play/lush with a desktop browser (Opera, Firefox) in GNOME it will tell you the default application to open the .pls file with. By default this is Totem. This application will then add both URLs (so #1 and #2) in the playlist. Rhythmbox, which you can also decide to use to listen to internet radio, has a seperate entry for the radio stations the user wants to listen to to which these URLs (again, both) are added and can be maintained. Allowing management and keeping them seperate is useful. Think of it: it is great to have your internet radio stations in your Media Player application on your mobile device. BTW, it'll play the http:// link fine including showing correct metadata artist and track.

Here on Diablo it works with Media Player (I never used this application before but it looks nice). However it doesn't show the metadata in the title bar above. It says 'Now playing'. Above the 2 playlists it says either: 'Playing: Lush: Mostly female vocals with an ele...' or it says: 'Playing: Carmen Rizzo - Easy Way Out (Featuri...'. It says either 1 of these 2, and switches every once in a while between these 2. Ofcourse when a new track is played it will show that track. Right now it has become 'Playing: Afterlife - Falling' which fits. You will notice what did not fit. From what I see here, with this version, metadata (internet radio station name, artist name, track name) is correct. I do get disconnected sometimes, but maybe that is my internet connectivity.
