Another option is to subscribe to/download the GMod Music Player addon, create the "gmmp" folder inside the garrysmod/sound/ directory (which is inside the directory where you installed GMOD) if it does not exist already, extract the .gma file of the BO6 AM music pack using gmad (the former can be found inside a folder named "3390261257" inside the directory of where you installed your workshop addons in (which typically ends with \SteamLibrary\steamapps\workshop\content\4000)), drag and drop all the audio files (which are .ogg files) into the "gmmp" folder, start and load into the game, open the GMod Music Player (by pressing F4 or typing !gmmp in chat), and pick the song you want to hear. This is a complicated process, but playing the song via GMMP is better than playing the song from the spawn menu.

Also, you could open up the spawn menu go to the left side to browse what track do you want to play by navigating to the Browse Sounds drop-down section, then the Addons drop-down folder, then the drop-down section for the BO6 AM pack called "Action Music: Call of Duty: Black Ops 6", then the am_music folder. In it, click on the folder of the type of the track do you want to hear, and then click on the track to play it. This is easier than repeatedly clicking the "Reshuffle Songs" button, but it would not work reliably well since playing the sound by clicking on it on the spawn menu would have it emit from your avatar, and it may stop playing at any moment.

The Action Music base always pick tracks at random, just like a random number generator. It does not allow you to pick a song you wanted to play, unlike Nombat. However, with a bit of luck, you can force the track type to what type you want to hear, since AM music packs seperate tracks into 4 types (Background, Battle, Intense Battle, and Suspense), unlike Nombat music pack that only seperates tracks into two types (Ambient and Combat), then repeatedly click on the "Reshuffle Songs" button to change the track until you hear the track that you want to hear. This is best done when you deactivate all the AM packs but the BO6 AM pack.

how do i pick the song myself quick question rry to bother you

ok ty and have a good day tryna rectare bo6 in gmod your addon will help big time

Another option is that after you load into the game, open the console and make sure that the cl_am_enabled_global is set to 1, which means that Action Music is enabled and can play tracks from the AM packs you are subscribed to.

You do not need a file extractor. To make sure it works, you just need to go to the spawn menu, go to the options tab in it, click on "Main" under the "Action Music" section, and make sure that the "Enable" checkbox is checked off. If not, then click on it.

ok ik that but like do i go to the spawn menu and play the tracks or do i need to do a file extract for it to work kinda what i was asking

This addon requires the Action Music base to work, as it's listed in this AM pack's required item. Once you have that base, all you had to do is subscribe to this pack (and make sure that it is activated), and then you're good to go.

OPTIONAL : To make sure that this pack is working, I recommend disabling all the other AM packs you have subscribed to, make sure you only have the BO6 AM pack and the AM base activated, load into the game, and make sure that the tracks from this pack is playing properly.

how do i use??
