MP3tunes has lost a copyright infringement lawsuit originally filed by EMI, however the judge tossed many of the record label's DMCA claims that were viewed as a threat to other music locker services. Judge William Pauley agreed that MP3tunes violated EMI copyrights by failing to remove pirated tracks from its customers' music lockers after pulling the same listings from Sideload.com, a music search engine that operated alongside the locker service.
