Who set the track?

Is there any information in wavelink who added the track/tracks to the queue

You can set Playable.extras with the requesters id that you can use to retrieve a member/user from your bot later.

Example:

track.extras = {"requester_id": 1234567890}

# Later...
requester = guild.get_member(track.extras.requester_id)

The same thing can be done on Playlist which will set extras to every track associated with the playlist.

do I need to do this before adding a track to the queue list?

[EvieePy]

Yes you would
