SAN FRANCISCO (AP) — A published report says Apple is orchestrating a $3.2 billion acquisition of Beats Electronics, the headphone maker and music streaming distributor founded by hip-hop star Dr. Dre and record producer Jimmy Iovine. The acquisition would add Beats Electronics' popular line of headphones and music streaming service to an Apple line-up that already includes iPods and the iTunes store, the world's top music retailer.
