Notes: 

1) Following files are in conflict and we have two versions each of these:
CeilingFan.3ds (jdl's interview level uses these, it seems he updated these for job interview collab)
CeilingFan.jpg
camera.png
7006.ogg (included in Music Extension Pack)

2) Deleted stuff
Blake's music pack deleted: https://pcpuzzle.com/forum/viewtopic.php?f=36&t=26776
Emerald's music pack deleted: https://pcpuzzle.com/forum/viewtopic.php?f=36&t=25669
Phoenix's music pack deleted: https://pcpuzzle.com/forum/viewtopic.php?f=36&t=27480

3) There's also custom music version of Robert Slayer's WonderScape Adventure #1: Cook's Assistant: https://www.pcpuzzle.com/forum/viewtopic.php?f=35&t=27954
It is not included as the music pack which it requires potentially conflicts with Robert's own music pack released earlier.
