OK, we won't tell anyone about all those downloaded music files you've compiled from the Internet. But now that you have those thousands of MP3 files, it's a shame that you can only listen to them at your computer.
But that's not the way it has to be. With network audio devices, you can stream your tunes to any room in your home, create multiple playlists, and never have to duplicate a single track! Share them right off your PC into every room!
