Loudeye Technologies has acquired Internet radio technology and infrastructure assets from OnAir Streaming Networks to improve its streaming music offering, which the company believes will boost authorized online music sales. Seattle-headquartered Loudeye did not disclose the financials of the deal. The newly acquired Web radio technology will promote online sales of CDs by allowing consumers to access authorized music over the Web. Loudeye recently inked a music-licensing agreement with Warner Music Group and BMG. In February, Loudeye acquired DiscoverMusic, which provides music to more than 80 e-tailers, including Amazon.com, BarnesandNoble.com, CDNow and Tower Records.
