As part of an ongoing major redesign on mobile, Shazam has just rolled out a new version of its iOS app. Adding to the changes we saw last month, today's update focuses on offering improved social sharing features, an even better lyrics experience and a more polished UI throughout the application. Users will now see in-depth artist biographies, redesigned album and song pages, as well as the inclusion of videos for songs. Shazam also points out that the app was also tweaked to have enhanced audio recognition and suck a little less power out of your iDevice -- much like Skype did recently with one of its apps. The update is initially only available for iOS, but the Android crowd can expect these revisions to come "in a couple of weeks."
