It wasn't exactly simple, but I made a decent-quality digital copy of a song I streamed on iTunes Radio using a Google Nexus 7 tablet and a new Android app. Honestly, I'm not sure it was legal to do so.\n\tI performed this feat using the\u00a0doubleTwist AirPlay Recorder\u00a0app. The app is from the developers of doubleTwist Music Player, another app that lets you sync your iTunes music library with your Android device. (I reviewed doubleTwist Player in March 2012 and liked it, though I did find some downsides.)\n\tThe goal of doubleTwist AirPlay Recorder is straightforward: "Record iTunes audio and radio to your phone or tablet!" In other words, you can copy a song you like from iTunes Radio to your Android tablet, where you can play it whenever you like it.\n\t(Image: DoubleTwist)\n\tI was also able to transfer the iTunes Radio track I captured to my Mac\u2019s iTunes library using the doubleTwist Mac app. From there, I copied it onto my iPhone. The track contains the artist name, song name, album name and album artwork. It\u2019s as if I purchased the track, but I didn\u2019t.\n\tIs this legal? DoubleTwist Co-Founder and President Monique Farantzos told\u00a0Engadget\u00a0that "recording has been around for decades, from audio cassettes (remember mix tapes?) to TuneIn radio's recording feature. Given that Apple built their iPod empire on letting millions of people rip CDs based on fair use, we don't see how they could object to this app." But is making a digital copy of a complete song without paying for it fair use? Maybe. But it feels wrong to me.\n\tOne thing that could prevent people from using the app for mass copying is the fact that you must record tracks in real time. If a song is five minutes long, the "ripping" takes five minutes.\n\tAlso, with iTunes Radio, you can\u2019t control when songs play\u00a0\u2014\u00a0unlike, say, Spotify. So ripping specific tunes also takes some effort and patience. DoubleTwist AirPlay Recorder also makes recordings in low quality (32 kbps). If you want better quality recordings, it\u2019s a $5 upgrade (for AAC VBR formatted recordings).\n\tIt will be interesting to see how Apple reacts to this app. In the meantime, though doubleTwist AirPlay Recorder does exactly what it promises, I don\u2019t intend to use it again for recording iTunes Radio tracks.
