Yahoo! Music Radio (formerly known as LAUNCHcast) is an Internet radio service offered by CBS Radio through Yahoo! Music. The service, formerly offered by LAUNCH Media, and originally developed by Todd Beaupré and Jeff Boulter, debuted on November 11, 1999, and was purchased by Yahoo! in October, 2001. LAUNCHcast combined with CBS Radio beginning on February 16, 2009.

LAUNCHcast allowed users to create personal radio stations or playlists of songs tailored to their musical tastes.

To create a personal station, users rated music on a 4-star or 100-point (depending on one's preference) scale. The service used those ratings to create a personal station of songs based on a user's favorite genres, artists, albums, and songs. The generated playlist contained a combination of rated and recommended songs. The ratio of rated/recommended songs could be specified by each user, but by default it was 50/50.

A recommendation engine suggested songs that might have matched a user's particular musical taste according to the following similarity criteria:
