Dr. Dre and Jimmy Iovine are taking on Apple's iTunes Radio, Pandora, Spotify, and others in the crowded streaming music field. This weekend, an affiliate of headphone company Beats Electronics announced a new streaming subscription service. It will launch in the U.S. on Jan. 21 and will cost $9.99 a month, the same as Spotify, after a free trial.

Backed by $60 million in investment, Beats Music's library has all the songs you'd ever want to listen to—20 million plus from all the major and independent labels. It's trying to distinguish itself from the crowded competition by focusing on personalization, curation and real life people—music industry veterans—to use their editorial expertise to deliver a custom music experience.
