Research In Motion has announced that anyone downloading the BBC Music application before January 4th will gain half a year's worth of free music, where those who have already downloaded the app will gain four months of free usage - which normally costs £4.99, each month.
BBM Music was launched in August and in beta, as a way to download tracks and share them with other BlackBerry users.
The service was officially launched in the UK mid-November, along with the BlackBerry Curve 9380 full touch screen phone and the Bold 9790 mobile.
BlackBerry Messenger Music allows the user to download 50 songs a month, which can be updated by swapping out 25 of them, every month.
These tracks can be shared with other BBMM subscribers, to build a cloud based music catalogue from the millions of songs on offer from companies such as Universal Music Group, Sony Music Entertainment, Warner Music Group and EMI.
