Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Yahoo! Music Jukebox is a freeware music player released by Yahoo! in 2005. Its appearance is vaguely similar to the MusicMatch Jukebox, related to the fact that MusicMatch, which developed the Jukebox, was purchased by Yahoo! in 2004. Recently it has been upgraded and renamed to Yahoo! Music Jukebox (from Yahoo! Music engine). Its features include CD ripping and burning, access to LAUNCHcast and the Yahoo! Music Unlimited music subscription service, playlist creation, transfer of music to select portable devices such as mp3 players and USB flash drives. The program allows Yahoo! Messenger users to stream music to one another (not to be confused with uploading and downloading or filesharing) and browse one another''s playlists. Only those subscribed to Yahoo! Unlimited can add entire songs to their collections, however. Non-subscribers are limited to a thirty second sample.
