Music Player help

[Scyobi_Empire]

I'm trying to get my music mod to appear in the music player but despite following the guide on the DD where it was announced, it doesn't show up in game

The file structure is

SYB_TLKOST
    descriptor.mod
    music
        (loose music files)       
        TheLastKingdomOST_MMCT.txt
        main_themes
            main_themes.txt
        music_categories
            music_categories.txt
    gfx
        interface
            illustrations
                music_player
                    syb_tlk_ost.dds

The music is all in the right file type and the custom main theme plays in game, could it be due to the categories text file being in the wrong format somehow? (see below)

category = {
    id = "syb_tlk_ost"
    name = "syb_tlk_ost_list"
    tracks = {
        "Icicle_MMCT"
        "Lighting_the_Beacons_MMCT"
        "Livstræðrir_II_MMCT"
        "Lívstræðrir_MMCT"
        "Shadow_Queen_MMCT"
        "The_Last_Kingdom_Slight_Return_MMCT"
        "The-Hall-of-the-Fallen_MMCT"
        "The-Last-Kingdom_MMCT"
        "Until_Valhalla_MMCT"
        "Blood_Will_Prevail_MMCT"
        "My_England_MMCT"
        "Blood_Moon_MMCT"
        "The_Beloveds_MMCT"
        "Aeternum_MMCT"
        "Banished_MMCT"
        "Blues_for_Halig_MMCT"
        "Death_of_Aethelflaed_MMCT"
        "Destiny-Is-All_MMCT"
        "Forever_MMCT"
        "Helig_MMCT"
        "Hymn_49_MMCT"
    }
}

Maybe you figured it out already, but the folder should be named music_player_categories, not music_categories. Also not sure if it will change anything, but the practice since RtP is to put the music definition files (ie. the TheLastKingdomOST_MMCT.txt file) inside an in_game folder within the music folder, rather than loose with the music files.
