Shazam has launched a new iPhone app called Shazam Encore, essentially a premium version of the company’s existing iPhone app, offering quicker tagging, music recommendations and charts, and a car mode to automatically tag tracks that are playing on the radio when driving. The Encore version costs a one-off download fee of £2.99, although Shazam says it will continue to support the free version too – albeit limiting new users of that to five tags a month in an effort to persuade them to upgrade.
