This mod replaces "SAMBA DE NIGHT" from Tekken Tag 2 with the Intro from Tekken Tag Tournament 2 (The Massive True Mix version)
I made an edit so the song would loop properly, i think it worked decently well.
Drop it in your mod directory and you're good to go -> "C:\SteamLibrary\steamapps\common\TEKKEN 8\Polaris\Content\Paks\~mods"
