My current setup at home regarding music is (still) based on iTunes, AirPlay and the remote App for iOS. I am using several radio strams from all over the world; my favourites stations at the moment are:

• Superfly (Vienna, Austria)
• LoungeRadio (Switzerland)
• Ibiza Sonica (Spain)

As these stations are not part of the standard list of radion stations in iTunes, I have to add the stream URL manually (by using FILE / OPEN STREAM). Today I had to look for a (new) valdid stream for IBIZA SONICA as the old URL was not valid anymore. I am happy to share the URL that works for me:
