Sharing a potential bug that's been in the release version of the mac desktop client for a while now. I'm probably an edge case user, but sharing anyway in case anyone else is running into this as well.
Steps to Reproduce:
1. Create a Playlist Structure Similar to the following, with 2 or more folders deep
... and so on
2. Double click "All Music"
*Works as intended until client is restarted, then bug re-appears
