iTunes Radio hasn’t yet overtaken the dominant music streaming services on the market, but there’s no denying that Apple’s entry has attracted a large number of users since launch. If you’re one of those users, doubleTwist’s freshly updated app can help you get even more out of your listening sessions by recording and saving audio streams from iTunes Radio for offline playback. The AirPlay Recorder functionality was already available for Android devices, but Mac users will now be able to take advantage of the feature as well. The app is free from doubleTwist’s website, and you can test it out by recording 10 second samples before you decide if you want to buy the full version for $9.99.
