I cannot reproduce this with a non-authenticated instance (YTMusic()). Is it only valid for authenticated accounts?

I can confirm that this only happens when using an authenticated account.

So work around as of now is to have two instances of YTMusic loaded. One authenticated and one not depending on the API calls.

I just tried with my authenticated main account (non-brand) and it's not failing either.

Did you interact with the albums in a special way? Add them to your library? Although that doesn't make them fail for me either.

Nothing special with these tracks. Previously I was able to reproduce the error 100% of the time on those select items. However, attempting the same action with the same demo file today I no longer get the error with any tracks. I'll chalk it up to google doing something strange.

Sorry for the distraction.
