调用方法：

QianQianLrcer loader = new QianQianLrcer();
        private void button1_Click(object sender, EventArgs e)
        {

           loader.SearchLrc(textBox1.Text,textBox2.Text);
//textBox1为演唱的人，textBox2为歌曲名
          // MessageBox.Show(((SongBase)(QianQianLrcer.listSongs[0])).Artist);
          // MessageBox.Show(((SongBase)(QianQianLrcer.listSongs[1])).Artist);


        }
QianQianLrcer loader = new QianQianLrcer();
        private void button1_Click(object sender, EventArgs e)
        {

           loader.SearchLrc(textBox1.Text,textBox2.Text);
//textBox1为演唱的人，textBox2为歌曲名
          // MessageBox.Show(((SongBase)(QianQianLrcer.listSongs[0])).Artist);
          // MessageBox.Show(((SongBase)(QianQianLrcer.listSongs[1])).Artist);

        }
