Lossless audio streaming is said to provide a better experience overall when listening to music, with CD quality and Hi-Resolution quality options. The first catch is you'll need to have a nice set of wired headphones to hear much of a difference in the first place. The second catch is that lossless streaming uses up way more data than regular audio streaming.
