Press the button or choose "Add All CD Tracks" from the "Playlist" menu to add all track of the currently loaded CD to the playlist. You can also drag CD tracks from the Explorer into the Raduga playlist.
Raduga uses the CD database of the Windows CD-Player. You will see the real song names after you have entered them in Windows CD-Player. To change the name of a song or to enter information about a new CD, select a CD track in the playlist and press the button or choose "Rename" from the "File" menu. This will open the CD database editor for the current CD.
