Shazam, the music discovery and tagging service, has rolled out an update to its iOS app that means whenever you tweet a song you’ve tagged to your followers, they’ll be able to play previews directly inside the message. This is thanks to Twitter’s Player Card, and works similar to how YouTube clips can be viewed without leaving the tweet.
In related news, the iOS app has also been updated with faster recognition, with claims that it can now recognize a song in as little as one second. The company says the speedier song identification will be more noticeable on the iPhone 4 and 3GS.
In addition to this, Shazam’s charts now display the most popular tracks of the past week, and some new “TV experiences” have been introduced for US users, though Shazam hasn’t specified what exactly this is.
