While remixes of famous ringtones are hardly new, YouTube musician MetroGnomes delightfully infectious iPhone more than merits a watch. The song is made up of some of Apples most recognizable sounds, including classic ringtones like Marimba, Opening, and Xylophone. It even features a cameo from Apples virtual assistant Siri. Make sure to watch out for the excellent guitar riffs that cap the three-minute video. On top of uploading his performance to YouTube, MetroGnome has also released downloadable versions of the catchy dance track for free.
