When I hear a song that I like but don't know its name, I think there are only 3 ways to get its name: 1) try to remember or write down part of the lyrics that I can hear clearly, then search it on the Internet (a bit cumbersome and inefficient); 2) walk over and ask somebody what the song's name is (somewhat inconvenient, and probably even the person playing or listening to this music knows nothing about it; 3) use an app like Shazam on a smartphone to intelligently, automatically, quickly and accurately identify almost any music being played anywhere!
