MP3 is dead, long live AAC

MP3, the format that revolutionized the way we consume (and steal) music since the 90s, has been officially retired -- in a manner of speaking. The German research institution that created the format, The Fraunhofer Institute for Integrated Circuits, announced that it had terminated licensing for certain MP3-related patents...in other words, they didn't want to keep it on life support, because there are better ways to store music in the year 2017. Rest now forever, MP3.
