The Web site of eStockMusic, owned by Jupitermedia Corp., has relaunched. Jupitermedia purchased the royalty-free music business at the end of an acquisition spree that also included the Steve Shapiro Music Library, Crank City Music and BBM.net. Starting with 1,100 wholly owned tracks, eStockMusic has grown to over 3,000 user-submitted themes, underscores, voiceovers, beats, loops and bumpers, licensed at micro-payment rates. The new site also includes expanded search capabilities and a directory of composers, offering flash developers and film and music producers a value-added resource. Other Jupiter Tunes brands include RoyaltyFreeMusic and StudioCutz.
