The current solution in iTunes
If you want to listen to local music files with iTunes, it will add them to your library automatically. But you don’t always want it to do so. For example to listen to the recordings of a friend’s last band rehearsal.
The approach of Simplay
My approach was to extract the audio player from iTunes, add basic features like controls, seek bar, queue, etc. and give it a clear and elegant GUI. The user can add songs by dragging them onto the player or double clicking them directly. To rearrange the Queue the user just drags songs to another position. The highlight color of the controls represents the colors of the album art. The seek bar displays the waveforms of the currently playing song.
