XM Satellite must defend a copyright infringement lawsuit brought by record labels owned by Sony BMG Music and EMI, a judge ruled. The suit is over an XM service that allows users to download libraries of songs. Once you download the songs, you will never need to purchase these songs from labels.

U.S. District Judge Deborah Batts in New York today turned aside XM’s request to dismiss the lawsuit, which accuses XM of copyright infringement and seeks undetermined monetary damages. She disagreed with XM’s argument that the service is akin to a traditional cassette player. (reporting by Cecile Daurat)
