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.

Google-owned Motorola Mobility has announced its sponsorship of pop star Justin Bieber’s ‘Believe’ worldwide tour.
