New audio features: Crossfading and S5 Stereo Pairing

• Crossfading: Create smooth transitions between songs just like the DJs do. With crossfading turned on, the volume at the end of the first song fades out as the volume of the next song fades in. You can select the crossfading playback mode from the Now Playing screen for any tracks in your music library, plus select music services including Last.fm, Napster, Pandora, and Rhapsody.
• S5 Stereo Pair setting: Perfect for parties or really large rooms, this setting allows you to group two S5s in the same room so one S5 serves as the left channel and the other as the right channel.
