For me, when you introduce new music or new song to me and if I love that song, the situation is almost equal like when Chinese people introduced paper to the Arabs. It’s like you’re introducing the new technology to me!
Same as technology, music can make my burden lifted, my life easier, and it can turn my mood. So, don’t hesitate to share a song which you might think very interesting for you to me. I will be more pleased if so few people know about that song. Just like what my friend said,”there’s a own satisfaction when you know a song that not everyone knows” :)
