Yahoo! Music Jukebox, formerly known as Yahoo! Music Engine, was a freeware music player released by Yahoo! in 2005 to compete with iTunes and Rhapsody in the digital music market. Developed side-by-side with MusicMatch Jukebox, another music player acquired by Yahoo! in 2004, it was designed to be the main client for Yahoo's array of music services, which were centered around Yahoo! Music Unlimited, a paid music streaming service and digital music store; in addition to being a music management software. In early 2008 Yahoo! sold off its music assets, including Yahoo! Music Jukebox to RealNetworks' Rhapsody and replaced it with a web-based music player.
