Mobile music discovery and interactive advertising business Shazam has appointed Rich Riley as its new Chief Executive Officer.

Former CEO Andrew Fisher, who led the company since 2005, has been appointed to the newly created position of Executive Chairman.

UK entrepreneur Brent Hoberman, best known as co-founder of lastminute.com, has joined the Shazam board of directors as an independent board member.

Shazam recently announced that its service had more than a quarter of a billion users and processed more than ten million tags per day, making it easier for consumers to identify songs and learn more about TV broadcasts.

As the end of the year approaches, so the volume of ‘real news’ tends to reduce as it’s replaced by annual reviews and seasonal surveys. We’ll be joining in with our predictions for 2013 in a few weeks’ time... but first, here’s a look back at the biggest stories from the past seven days.

Shazam, the ‘media engagement’ company best known for its mobile music tagging technology, has published details of the most-tagged songs of 2012 and revealed its predictions of music artists it expects to hit the big time in 2013.

By comparing information about ‘breaking’ artists with trends indicated by Shazam’s data, the company expects French Montana, Bei Maejor, Aluna George, Joey Bada$$, Becky G, Angel Haze, Rhye, Tito Lopez, Baauer and Haim to become increasingly popular in 2013.

Although last week's Apple iPhone 5 announcement dominated the headlines, there's still plenty more to talk about.

We have a prediction about the billionth Android handset, we look at Acer's cancelled smartphone launch and we discuss the growth of mobile messaging.
