On January 21st, Beats Music will arrive on iOS, Android, Windows, and the web for a $9.99 monthly subscription. The service, originally known as Daisy, uses a combination of algorithms and human curation to suggest songs, and claims to have a staff of music experts hand-selecting your playlists while you stream. The companys betting that curation will set Beats Music apart from the music streaming competition, like Spotify and Rdio, and its not alone in that bet — as rumored, ATT has an exclusive partnership with Beats Music for a special $14.99 a month family plan. While the standard $9.99 monthly subscription lets a single user stream songs to three devices, the ATT-exclusive $14.99 family plan will let five users stream to ten devices in total. Youll also need to have a cellular family plan through ATT, though, or a multiline account of some other sort.
