Last week, we published a quiz testing listeners on their ability to discern between lossless audio and compressed mp3s. We picked six songs from different eras and genres: an early digital recording of a Mozart piano concerto, an a cappella version of a pop song, the billionth song ever sold on iTunes, the most-streamed song of 2014 and two songs from musicians who happen to own digital music services.
