I would like to buy the soundtracks of every game of the Silent Hill series. I was able to purchase 1, 2, 3 and 4 on iTunes but apparently there was some huge legal fight between Konami and Akira Yamaoka in 2020 which led to the delisting of the soundtracks for Shattered Memories, Origins, Downpour, Homecoming and Book of Memories. Where can I purchase the complete soundtracks for every game? Or at least a site where they are available for download?
