A bevy of rock stars, record label executives and fans of the embattled Napster Internet song-swapping service are due to appear before Congress on Tuesday for a Senate hearing on online entertainment and copyright issues, reports Reuters. Among those expected to testify in favor of Napster are former Eagles member Don Henley and former Public Enemy rapper Chuck D. Expected to take the opposing side are ’70s rocker Ted Nugent and EMI exec Ken Berry. Word also broke yesterday of a possible song-swapping service from Bertelsmann AG, EMI and AOL Time Warner (which owns PEOPLE, among other holdings) — all of whom might team-up with RealNetworks to create a Napster-like service called MusicNet. Meanwhile on Monday, Prince announced that he plans to premiere a new song, “The Work — Pt. 1,” on Napster on Friday, becoming one of the best-known artists to embrace the controversial Internet music-sharing service as a means of promotion.
