RealNetworks, the Seattle-based digital media services and software company, announced today (April 15) that its Internet jukebox and radio subscriber services, Rhapsody and RadioPass, added 100,000 customers in the first quarter. RealNetworks' overall subscriber base has increased by 80% in the past two quarters and now totals 450,000.

The news comes nearly a year after RealNetworks announced its plans to acquire Listen.com and the Rhapsody service.

Real estimates the total universe of paid subscribers to on-demand and radio services -- including those of its competitors -- to be 880,000.

Rhapsody delivers unlimited access to music from major and independent labels, with more than 625,000 songs available for on-demand streaming and more than 550,000 available for purchase at 79 cents apiece.

RealNetworks will release financial results for the first quarter of 2004 on April 28.

The news comes on the same day it was reported that RealNetworks is lobbying Cupertino, Calif.-based Apple Computer to join forces against Microsoft in the digital-music market.

In trading on the Nasdaq today, RealNetworks shares fell six cents to $6.64.
