酷狗top500爬取时出现IndexError: list index out of range

求帮忙，因为需要爬取酷狗top500的历史数据，在网上找到了一个爬虫代码，运行时出现下列问题。
经过查询，感觉是因为某一行数据中没有“-”符号导致的错误，请教大家要怎么修改代码，万谢！

import requests
import agent    # 调用agent模块(自己创建的模块）
from bs4 import BeautifulSoup   # 引用BeautifulSoup库中的bs4函数
import time
import xlwt



def spider(url, data, count):   # 文件爬取
    try:
        r = requests.get(url, headers=agent.getheaders(), timeout=10)   # 发出请求，设置代理，与超时时间
        soup = BeautifulSoup(r.text, "html.parser")
        ranks = soup.select("span.pc_temp_num")
        titles = soup.select("div.pc_temp_songlist>ul>li>a")    # 注意获取到的内容是以列表的形式
        times = soup.select("span.pc_temp_tips_r>span")
        for rank_s, title_s, time_s in zip(ranks, titles, times):
            data.append([])
            count += 1
            data[count].append(rank_s.get_text().strip())
            data[count].append(title_s.get_text().split("-")[0])
            data[count].append(title_s.get_text().split("-")[1])
            data[count].append(time_s.get_text().strip())
            print("排名:{}\t歌手:{}\t歌曲:{}\t时长:{}\t".format(data[count][0], data[count][1], data[count][2], data[count][3]))
            #time.sleep(1)   # 设置睡眠时间，限制爬取网站数据速率,休眠一秒



    except():
        print("爬取失败")



def save(data):  # 文件存储
    try:
        book = xlwt.Workbook(encoding="utf-8")  # 设置格式为utf-8,创建工作薄
        sheet = book.add_sheet("Sheet1")  # 创建工作表
        titles = ['排名', '歌手', '歌曲', '时长']
        for t in range(len(titles)):
            sheet.write(0, t, titles[t])
        i = 1
        for x in data:
            j = 0
            for y in x:
                sheet.write(i, j, y)
                j += 1
            i += 1
        book.save("text.xls")  # 保存文件



    except():
        print("Data Error")


def main():
    urls = ["https://www.kugou.com/yy/rank/home/{}-8888-40200.html?from=rank".format(str(i)) for i in range(1, 24)]  #循环创建地址
    datas = []
    count = -1
    for url in urls:
        spider(url, datas, count)
        count += 22
    save(datas)


if __name__ == "__main__":
    main()

Traceback (most recent call last):
  File "/Users/arlen/PycharmProjects/pythonProject3/main.py", line 67, in <module>
    main()
  File "/Users/arlen/PycharmProjects/pythonProject3/main.py", line 61, in main
    spider(url, datas, count)
  File "/Users/arlen/PycharmProjects/pythonProject3/main.py", line 21, in spider
    data[count].append(title_s.get_text().split("-")[1])
IndexError: list index out of range

进程已结束，退出代码为 1

21、22行代码处重复了吧
打印下看title_s.get_text().split(''-")只得到数组长度为1呢

加个判断或者捕获这个异常
