Many times, when we are watching a TV show, we fall in love with the background music, but cannot find it after searching online. So what to do? We can use our brains to remember this melody (in simple words); if there are too many instruments mixed in it or you can't remember the feeling, then you can record it with your mobile phone, so that you can listen to it over and over again and get a sense of the mood. Why not? Hope it will be adopted, thank you.
