Spotify's iOS app has just received a major boost: all songs can now be streamed at 320 kbps, the same as the desktop version, compared to the previous upper mobile limit of 160 kbps.

Spotify calls it "Extreme" quality, but regardless of the name, it will make listening with decent headphones a pleasure. No word on when it's coming to Android and Windows phones, though. [Spotify for iOS via The Next Web]
