#duelingo - Learn a song, sing a language!

According to a study from three Boston-based universities, our ability to learn a new language is strongest “until the age of 18”. Even though learning an entirely new language may get tougher, our ability to involuntarily remember songs remain with us for a long, long time. Hence, Duolingo brings #duelingo, a new way of learning languages - through karaoke experiences of the songs we already know, to duel with people we love to sing along with.
