Apple's iTunes Radio has already picked up 11 million listeners since its launch last week, Apple announced Monday.
Available through iTunes 11 and iOS 7, iTunes Radio takes a page from Pandora's playbook. You can create and add different music stations to your feed based on your tastes and listen to songs streamed from each one. You can fine-tune each station to play only hits, a variety of songs, or a "discovery" of music new to you.
Apple also naturally makes it easy to buy any song via iTunes with a price tag that you can click on to make your purchase. So far, the most popular song is "Hold On, We're Going Home" by Drake, according to Apple.
iTunes Radio is currently available just in the United States.
Apple also announced today that more than 200 million devices are now running iOS 7, while iPhone sales surpassed 9 million during the launch weekend of the new 5S and 5C.
