Originally created by @soreikomori on GitHub (Jun 21, 2024).
Original GitHub issue: https://github.com/sigma67/ytmusicapi/issues/604

Describe the bug
When attempting to run yt.get_playlist(), the program goes through all of the steps until it lands in line 97 of navigation.py, where it errors out:

root = root[k]
           ~^^^
KeyError: 'singleColumnBrowseResultsRenderer'

Just a moment ago, YTM seems to have pushed an update that makes playlists look different on browser. This random change might have caused some internal issue in the Google TV API that ytmusicapi fails to handle appropriately.

To Reproduce
Steps to reproduce the behavior:

  1. Use yt.get_playlist(), for example by running yt.get_playlist(id, None) where id is the ID of a playlist (string).
  2. Get the error.

Additional context
Here's how the entire error looks like for me.

I was using 1.3.0 for the above. Didn't realize I was so far out of date. I just upgraded and am dealing with an issue that must be in my code but I will try to get it working and see what happens with the latest version.

I tried on 1.5.2 and 1.6.0 and got the same error on both. Upgrading to 1.7.3 seems to have fixed it fortunately. I'll leave the issue open for now though given what @JohnHKoh reported above.

github.com/sigma67/ytmusicapi@11823d6387/ytmusicapi/mixins/playlists.py (L214-L215)

These seem to be the offending lines. I don't know what it looked like before, but second_subtitle_runs[has_views + 0]["text"] is "트랙 100개". Therefore song_count[0] now returns "트랙" (track) instead of "100개". This seems to be a localization issue, as when I change the language from Korean ("ko") to English ("en"), second_subtitle_runs[has_views + 0]["text"] is "100 tracks", and so song_count[0] now gets the correct value.

The code will need to be updated to extract the number from this string.

I'm impressed that there are still people on 0.25. As it's fixed on latest I will close this thread.
