我有pyspotify的问题。我正在尝试搜索艺术家名称，获取他们的顶级曲目列表，然后播放其中一个。这是我的代码段：
search_string = "artist:"+artist_to_find
result = session.search(search_string)
result.load()
print result.track_total
browser = result.artists[0].browse()
browser.load()
print browser.tophit_tracks
for track in browser.tophit_tracks:
print track.name, track
toptracks = browser.tophit_tracks
print "error check"
if toptracks!=-1:
print "------------------"
tracktoplay=choice(toptracks)
rand = randint(0,10)
print "random track number = %s" %rand
tracktoplay = browser.tophit_tracks[rand]
print tracktoplay.link
print tracktoplay.name
print "------------------"
session.player.load(tracktoplay)
session.player.play()
我经常在没有先前曲目完成的情况下调用此代码。 Perodically（每隔几个轨道）我收到以下错误：
random track number = 7
spotify:track:6vQN2a9QSgWcm74KEZYfDL
Take A Chance On Me

任何人都可以建议我做错了吗？
