I love to be experimental with my music replacers! For me, I think it's about changing how the player feels, rather than how the game *feels* or sounds. This is especially true when taking music from games that people are nostalgic for.

if the Metal Slug ost replacer I could rationalised like war and all, this one I don't get at all LOL
but I love Tekken's ost a lot, especially 4th, so thanks anyway!
