Imagine hearing a song on the car radio, being able to save the artist and album data, and then downloading the song to your iPod at some point later on. Not long ago, this kind of technology was a pipedream but, like the robot apocalypse, the march of technology can't be stopped. There are already apps for the iPhone and Android that can tell you what song you're listening to, but trying to use these programs while driving isn't something we'd advocate. Instead, try the built-in iTunes song tagging feature found in many Ford and Lincoln vehicles. Rather than just listening to "Tubular Bells" from "The Exorcist" or "Main Title" from "Terminator 2" on SIRIUS XM, tag it and download it later. You'll make the soundtrack to your life way more dramatic...or creepy.
