After months of contract negotiations with record labels, Apple has finally announced its Pandora-killing music app called iTunes Radio. The new music service will be built into the official iOS Music app. Much like Pandora, iTunes Radio lets you create your own music stations simply by typing in names of artists. While you’re listening to a song that you like, you can make it a favorite by clicking a star icon and iTunes Radio will start playing more songs like it. iTunes Radio will be free and supported by ads although users can get an ad-free version of iTunes radio if they’re already subscribers to iTunes Match. Apple says that the new service will launch first in the United States before expanding to other countries.
