Step aside, Spotify and Rdio - Apple is making its entrance in the magnificent new world of online radio streaming. iTunes Radio is a service included in the new iTunes that will also simplify the buying process: listeners can click the "buy" button as a track plays, or purchase it later from their listening history.

The system is similar to Pandora's, which allows the user to choose an artist to base a station off of, and will then intelligent play similar music that it thinks they might like. Featuring ads for the non-paying users (a $25 annual subscription will stream the music ad-free), iTunes Radio is already included inside iTunes 11.1, now available through Apple’s website.

Today also sees the launch of iOS7. Just in case you didn't know.
