Birmingham radio listeners have helped to pioneer a new technology that could change the way music is bought.
One hundred people in the city are currently trialling the Digital Music Download (DMD) system which allows listeners to download and buy tracks as they hear them live on digital radio.
According to UBC Media, the company that developed the technology, initial feedback has been good with participants downloading on average four tracks every day.
London-based UBC tested the new system using the digital version of Chrysalisowned 100.7 Heart fm.
Tracks can be downloaded directly to any computer or mobile phone that can play digital radio.
It will also store the music online, so that it can be transferred to an MP3 player, such as an iPod.
Simon Cole, chief executive of UBC Media, said: "People are buying music online - fact.
"People are listening to the radio on their phones - fact.
"This service allows people to buy music as they listen on the move. You can't argue with a compelling proposition like that."
The service, which has taken a seven-figure sum to pilot, plans to go live across the UK later in the year.
When it launches it will only be available to Heart listeners, but UBC hopes DMD will eventually be available for a number of radio stations.
