Apple\u2019s walled garden can be a nice place to live. But at some point, you may want to venture beyond the cozy confines of Cupertino\u2019s ecosystem. Unfortunately, that\u2019s when you could find yourself straying into the battlefield that is the ongoing Apple-Google skirmish. And you'll probably find yourself asking the following question sooner than later: How can I pack up my iTunes music library and move it to a device from Apple\u2019s arch nemesis Google?\n\tSan Francisco-based doubleTwist\u2019s doubleTwist Player offers a truce, of sorts. The company\u2019s free Android application (current version: 1.7.2), coupled with its free Windows and Mac desktop software, copies your iTunes music and video to your Android device\u2014with a few limitations.\n\tLet\u2019s start with the \u201cfree\u201d part. Yes, the doubleTwist Player app lets you transfer content to your Android over USB. But if you want to sync wirelessly, you\u2019ll need the not-so-free doubleTwist AirSync app ($5). Want to download album art or subscribe to podcasts for automatic downloads? Those are premium features as well that cost $5 each. Your best bet: Download doubleTwist Player and upgrade within the app to doubleTwist Pro, which gives you all those features for $10. It\u2019s worth the price. (The screen shot below shows the Android app in play mode.)\n\tBut back to those limitations. Be aware that any iTunes music or video protected by DRM won\u2019t be transferred. This applies to songs you purchased in 2009 or earlier, before Apple discontinued its music DRM. In iTunes, you can upgrade purchased songs with DRM to \u201ciTunes Plus,\u201d which strips away the restrictions. Also, the doubleTwist desktop software lets you know which content is protected by displaying a padlock icon next to any content with DRM.\n\tAnother heads up: You can\u2019t copy over TV shows or movies acquired through iTunes, either. Videos of your own making, however, will cross the divide, though the process isn\u2019t entirely intuitive. In the desktop app, you must click on \u201cVideos\u201d under \u201cLIBRARY,\u201d find the video file you want, drag it to a new or existing playlist, click your Android device\u2019s name under \u201cDEVICES,\u201d click the checkmark box next to \u201cSync videos to device,\u201d find the playlist by checking \u201cSelected Playlists,\u201d click to select the playlist by name, then click the \u201cSync\u201d button.\n\tTo recap: There\u2019s a fair amount of setup, the free app will probably end up costing you money, and you still can\u2019t copy over everything in your iTunes library. Also, doubleTwist Player isn\u2019t the only app of its kind\u2014Highwind Software LLC\u2019s TuneSync ($6) and JRTStudio\u2019s iSyncr for Mac and iSyncr for PC ($3 each) are other options. All that aside, if you\u2019re a music lover moving from iOS to Android (or toggling between the two, as I do), this app ultimately does a nice job of helping you scale Apple\u2019s garden wall\u2014even if you have to leave a few things behind.
