/*playlist group IDs (pgroup_id) is a group identifier that is implicitly
* or explicitly assigned to playlists so they can be associated with each other.
*
* For example, when you switch a track's playlist, you can choose to
* switch other tracks to the same pgroup_id
*
* pgroup_id's should be unique; currently we use a timestamp to avoid duplicates.
* pgroup_id's are human-readable strings; use string comparison to find matches.
*
* To be useful, we want every playlist to be assigned a sensible pgroup_id
* Some examples of pgroup_id's getting assigned *explicitly* include:
* when the user makes a new playlist for a track or Track Group
* when the user triggers an action like "new playlist for rec-armed tracks"
* Some examples of pgroup_id's getting assigned *implicitly* include:
* the user makes the first recording pass ("take") in an empty playlist
* the user imports tracks.
