2001- 2009: LAUNCHcast powered by Yahoo! Music
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.
