微信公众平台的消息接口-音乐消息，这是广大微信公众平台开发者的福音。 根据这一功能，如果能做出在微信中点歌功能，那么我们以后就可以不用安装其他APP， 直接在微信里面关注一个账号，就可以听歌了，还省去了安装的麻烦，而且不用再占用空间。如果音乐资源足够好，那将秒杀一切手机上在线听歌软件也不是没有可能的。

                    }
                }catch(Exception $e){
                }
            }
            return $content;
        }

接口调用:

include ('music.class.php');
$m = new MusicApi($musicContent);
$mArr = $m->getMusicInfo();
return $this->responseMusic($mArr["Title"], $mArr["Description"], $mArr["MusicUrl"], $mArr["HQMusicUrl"], 0);
