Crossfade between tracks.

This is a setting that is also available in Samsung music, where you can choose a certain amount of seconds up to 10. Than the current track you are listening to will flow into the next track. For example, if you set it to 10 seconds, than when 10 seconds are left of the current track, it will start the next track, but still finish the last 10 seconds of the track you were first listening to. This creates a better flow of the music and stops some of the silence inbetween tracks. I've used this feature in Samsung music and I love it, and is perfect when you leave your playlist on shuffle.
