If you like music from the 40s, 50s and 60s, then you should check out this application. It contains a list of various radios that are broadcasting music from that period. You can choose to listen to the music you like. It's very easy to use, just tap on the radio you want to listen to, and you can start listening.

The application also has an integrated media player, which allows you to view the artist and the track title of the song that is currently playing. This is very convenient, because you don't have to open a separate application to view that information.
