        public bool downloadStMusicFile(string musicRealAddr, string fullnameToStore, out string errStr, Action<int> funcUpdateProgress)
        {
            bool downloadOk = false;
            errStr = "未知错误！";

            if (musicRealAddr == null || 
                musicRealAddr == "" ||
                fullnameToStore == null ||
                fullnameToStore == "")
            {
                errStr = "Songtaste歌曲真实的地址无效！";
                return downloadOk;
            }
            
            Dictionary<string, string> headerDict = new Dictionary<string, string>();
            //headerDict.Add("Referer", "http://songtaste.com/music/");
            headerDict.Add("Referer", "http://songtaste.com/");

            //const int maxMusicFileLen = 100 * 1024 * 1024; // 100M
            const int maxMusicFileLen = 300 * 1024 * 1024; // 300M
            Byte[] binDataBuf = new Byte[maxMusicFileLen];

            int respDataLen = crl.getUrlRespStreamBytes(ref binDataBuf, musicRealAddr, headerDict, null, 0, funcUpdateProgress);
            if (respDataLen < 0)
            {
                errStr = "无法读取歌曲数据！";
                return downloadOk;
            }
