Sony revealed that it was adding a streaming music service to PlayStation Portable handheld gaming gadgets next week.

A Music Unlimited service powered by Qriocity will let PSP users with PlayStation Network accounts tap into a library of millions of songs stored on computers in the Internet "cloud" beginning April 14, according to Sony.

PSP devices will need to be connected wirelessly to the Internet at "hotspots" to access tunes, according to the Japanese consumer electronics titan.

The service already streams music to personal computers and an array of Sony devices including newer model Bravia televisions, Blu-ray disk players and videogame consoles.

"PSP owners can also enjoy a common and synchronized music experience on their PS3 systems as well as PCs and other network-enabled Sony devices without the need to manage or transfer ," Sony said in a release.

Sony charges a $3.99 monthly subscription fee for basic Music Unlimited service, which offers commercial free listening.
