This app is like RDS (Radio Data System) in your phone.
It shows the radio stations playlists in the real time Say you are driving the car and your car radio has no RDS, so you use onRadio app to see what song is playing or what was played before or what is playing right now on the other station. If there is YouTube video for the song in playlist you can watch it!
Radio can be searched by name, call letters, frequency, genre, location.
App is powered by yes.com.
In the future releases (possibly): auto-update for the saved playlists; song/artist/album info; lyrics; more integration with YouTube; ability to buy the song/album.
