CoStar Group subsidiaries

L Q Corporation was founded in 1996 and is headquartered in New York, New York. They provide a leading open platform that enables the digital delivery of music over the Internet. Their software products and services give artists, record companies, websites and retailers the ability to create, syndicate and sell recorded music with copy protection and copyright management. Through their Liquid Music Network website affiliates, they help artists and record companies promote and sell their recorded music. From their growing catalog of syndicated music, consumers can preview and purchase digital music. Consumers then can transfer downloaded music to recordable compact discs and, later in 1999, to digital consumer devices. Their solution is based on an open technical architecture that is designed to support multiple leading digital music formats, including mp3 and Dolby AC-3. Numerous recording artists and record companies have used their platform to promote music releases including BMG North America, Capitol Records, Columbia House, Dreamworks Records, EMI Classics, Bruce Hornsby, The Dave Matthews Band, Sarah McLachlan and Rounder Records.
