iTunes Radio channels have been folded into Apple Music

As previously announced, Apple has discontinued its free, ad-supported iTunes Radio channels, which have been folded into Apple Music. However, Apple's Beats 1 radio channel remains available to iTunes users as a free listening option. 

Apple Music costs US$9.99 per month or $14.99 per month for up to six people in a household. There’s a three-month trial period so you can give it a try.

Apple bought the steaming music service Beats Music, and Beats Electronics — which makes the  Beats headphones, speakers and audio software — in 2014. Apple acquired the two companies for a total of $3 billion, consisting of a purchase price of approximately $2.6 billion and approximately $400 million that will vest over time.
