About: (Est. 2002) “Shazam is a commercial mobile phone based music identification service, with its headquarters in London, England. […] Shazam uses a mobile phone’s built-in microphone to gather a brief sample of music being played. An acoustic fingerprint is created based on the sample, and is compared against a central database for a match. If a match is found, information such as the artist, song title, and album are relayed back to the user. Relevant links to services such as iTunes, YouTube, Spotify or Zune are incorporated into some implementations of Shazam.” (Source: Wikipedia)

Ed.’s Notes: Although I always hate the combination of upper and lowercase letters this ends up being a decent wordmark and the icon is much improved. A few more images of the icon and its construction below (or after the jump).

Provided quote: “We were thrilled to help Shazam transition from an app used to tag songs to a broader platform of discovery for TV, music, movies, live events and more. The new brand draws from the iconic loading disc that pops up when the app is listening. All of the new elements were derived from that expression, which we’ve enriched and made more responsive.”
