Spotify today released a new version of their software which contains new functions like Gapless playback and Crossfade. With Gapless playback activated the tracks will flow seamlessly without any silence between them. This is nice when listening to classical music, live recordings or concept albums.
Another new feature is Crossfade which mixes songs by creating transitions from one song to another. Crossfade can be described as an auto dj that mixes the music for you to avoid interruptions.
