The king lives! Or at least, he can keep you company at work.

Digital music service provider MusicNow on Tuesday launched an all-Elvis online radio channel that offers up more than 2,000 songs by one of rock's most enduring legends, available on demand. The channel, called Elvis 2nd To None, after a CD collection to be released this fall, makes Elvis Presley's song library available as streams or downloads. MusicNow subscribers can pay $4.95 a month for unlimited access to more than 40 streamed radio channels or $9.95 to add unlimited downloads from the service's collection of songs from all five major recording labels.

Elvis 2nd To None follows MusicNow's recent launches of channels devoted to Blue Note Records' jazz collection and the music of Quincy Jones. The service uses digital-rights-management software to ensure that rights holders for all the music it distributes are compensated, offering a legal counter to the popular file-sharing services that have been the subject of an aggressive subpoena campaign by the Recording Industry Association of America.

While file-sharing gets the bulk of the attention and is thought to be draining corporate network resources as employees build illicit digital music collections, Jupiter Research analyst Lee Black says use of Web-based radio is actually more widespread in the workplace--and thus is more likely responsible for hogging companies' bandwidth.
