Replacement method :
First you need to install the VPK unpacking tool

step 1: Subscription It,Enter the game and wait for the file download to complete and exit the game

step 2: Open folders in sequence
Steam\steamapps\common\Left 4 Dead 2\left4dead2\addons\workshop
Find the VPK file you just subscribed to, open it and unpack the contents to a new folder

step 3:Open the folder, root\media, Copy 4 copies of the file shinobu1.bik or shinobu2.bik, rename the five vpk files to l4d2_background01~05, and copy the files

step 4:Open folders in sequence
Steam\steamapps\common\Left 4 Dead 2\left4dead2\media
Paste the copied file over the original file
(I recommend backing up your files first)

step5 : Open folders in sequence
Steam\steamapps\common\Left 4 Dead 2\left4dead2\sound\music\l4d2
Delete all files inside (I recommend backing up first)
This step is to avoid conflict with the original menu background music
