Mexican operator Iusacell is letting its subscribers “rent” their music; they can play, rewind and file as many songs as their devices can hold for the length of time they pay for the service.

The service is called Music Box and was developed by eMbience. The music service for the Mexican market delivers full songs from the Sony and Warner Bros. libraries and can be downloaded across all handset levels. Subscribers can also access ringtones, wallpaper and other assets related to the downloaded music.

The eMbience platform includes a BREW-based music player for downloading full-track stereo songs, which can be stored for the subscriber on a carrier-based Web server for delivery on-demand. Songs purchased on-demand will be immediately downloaded over-the-air. Users can store an unlimited number of songs or music clips.

Cost of the service was not immediately available.
