Python Pyspotify-周期性“无法播放曲目错误”

我对pyspotify有问题。我试图寻找一个艺术家的名字，得到他们的顶级曲目列表，然后播放其中一首。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()

我经常调用此代码，而没有前面的轨迹整理。每隔几轨，我就会出现以下错误：

random track number = 7
spotify:track:6vQN2a9QSgWcm74KEZYfDL

  File "/usr/local/lib/python2.7/dist-packages/spotify/error.py", line 30, in maybe_raise
    raise LibError(error_type)
spotify.error.LibError: The track cannot be played

谁能告诉我我做错了什么

谢谢

我对pyspotify没有经验，但我是出于好奇才看的

如果我是你，我会在调用play之前检查是否已加载

希望能有所帮助。

谢谢您的评论。我试着为正在加载的轨道添加一个检查，但没有帮助。如果为True:if session.player.state=='loaded'：break我发现从libspotify SP_session_player_play函数中获取的错误SP_error_TRACK_不可播放。我已经黑了spotify库中的code player.py，以报告卸载，而不是错误，如果失败，我的代码将重新尝试，但是有人能告诉我为什么一首曲目会被视为不可播放吗？当我获取链接并在浏览器中播放时，链接有效，曲目播放没有问题。任何帮助都将不胜感激！
