Do you remember rock n’ roll radio? If not, we won’t take it personally. After all, with services like Spotify, Rdio, Slacker and Turntable.fm to choose our tunes from, computer and smartphone users have never been more spoiled for choice when it comes to music. Commercial-free music is available to anyone that wants it, provided they’re willing to do the work of setting up an account and picking the tunes they want to listen to. For those of us that prefer to sit back and let someone else do the aural heavy lifting for us, and consider radio to still be an important part of our daily lives, there’s Radio, our Chrome Web App of the Week.
