Walking down the street will always hear the voices of these stars floating in your ears, your mp3 player must have kept a lot of their favorite pop songs. Why their songs are so popular, because of the popular chant! In the bird kingdom, the same applies to the most popular birds will get the birds MM their favor, and those outdated tune but did not cause bird's interest Oh.
