@hj @sicp @mer original OST is a lot of copyrighted samples that have a pretty much 0% chance of being properly licensed, which is a non-issue for non-commercial products, but a potential product-ending issue for commercial products. im sure some OG songs are OK licensing wise but it is what it is
for example Pepper Steak (the combat song) is sampled from a song of the same name and another song, and there's plenty other unknown samplings from many a songs. its safe to assume that 10 years after making most of those songs, coldwood (song author) would not remember whats safe, whats maybe safe, and whats unsafe to use commercially
im sure there's other reasons for a new OST too, but this would be a critical one
