Online music service Napster has joined forces with satellite pay-radio station XM to enable its subscribers to buy the music they hear.
'XM + Napster' is set to launch in the fourth quarter of 2005
The deal is intended to take advantage of next-generation MP3 players which also receive satellite radio stations.
The XM/MP3 digital music players will let users bookmark songs they hear on the radio for future purchase online.
Analysts have long said satellite radio stations would converge with music players and other portable devices.
In February, Sirius Satellite Radio Inc said it had held discussions with Apple about adding its service to iPods.
XM launched its MyFi portable radio device in October.
At the time, XM's chief executive Hugh Panero said he believed that portable satellite players and portable music-storing players would one day be combined.
Shares in Napster and XM rose on Wednesday morning by 25 cents and 48 cents respectively.
