Left 4 Dead 2 Custom Music Problem

[ZeroEightThree]

Hi, ive been having problems lately with my custom level im making for Left 4 Dead 2 called Left4tanker (It started off as a test, grew to like it and couldnt be asked to change the name to something less generic) and when it comes to making the music play at the certain events their sopposed to, like during the start of the level, it doesnt seem to work.

I have followed the Valve Developer wiki properly and the game recognizes the music and plays it when i tell it to through the console but the game just doesnt seem to play it when the events they are sopposed to play on occur.

Here is the code for the txt file located in the Left4Tanker/maps folder called Left_4_Tanker_Level_Sounds.txt

"Event.MissionStart"
{
    "channel"        "CHAN_AUTO"
    "volume"        "VOL_NORM"
    "pitch"        "PITCH_NORM"
    "soundlevel"    "SNDLVL_NORM"
    "wave"        "Start.wav"
}

"Event.FinalBattle"
{
    "channel"        "CHAN_STATIC"
    "volume"        "3.0"
    "soundlevel"    "SNDLVL_NORM"
    "wave"        "Yelldeadcell.wav"

    GameData
    {
        "MusicTrack"            "default"
        "MusicPriority"            "HIGH"
        "MusicFadeOut"             "2.0"
        "MusicBlockTrackList"   "zombat, zombat2, zombat3, zombatIntro, ambient, tank"
        "MusicStopTrackList"    "zombat, zombat2, zombat3, zombatIntro, ambient, tank"

    }
}
    
"Event.ScenarioWin"
{
    "channel"        "CHAN_STATIC"
    "volume"        "1.0"
    "soundlevel"    "SNDLVL_NONE"
    "wave"        "Yesterday.wav"
    
    GameData
    {
        "MusicTrack"            "default"
        "MusicMaster"           "PLAY_TO_END | DONT_DISENGAGE"
        "MusicPriority"            "CRITICAL"
        "MusicParameters"        "AFTER_DEATH | AFTER_MISSION_END"
    }    
}

Everything seems in order and ive done everything such as building the cache file and setting the map to load this file but it doesnt seem to be working, does anyone have any ideas on how to get the music working?
