Quest for Fame is a music video game developed by Virtual Music and distributed by IBM. They were eventually acquired by Namco (who then made the arcade version in 1999) to create karaoke machines. In 2001, they resurfaced with a web-based subscription product named Music Playground, allowing the user to purchase the instrument tracks for already-owned audio CDs and play along with them. The service failed to attract a sufficient number of users and was finally shut down in August 2003. Source: Wikipedia, "Quest For Fame", available under the CC-BY-SA License.
