Oh I'm fully aware of these. 3S and 3NG at least sound like they belong in a fighting game.You should listen these OSTs, seems somewhat a mixture of them:
I also think that as happened in SFV they'll add a ton of music tracks and remixes for characters and stages. Including original and remixed classic tracks.
These are like the MVC2 stuff, but worse, since they were good Jazz.
Most just sound like poorly remixed stuff to sound "urban" and call it a day.
To me, SF music is generally great, but KOF takes it for my tastes as the best OST for a fighting game franchise so far, followed closely by Guilty Gear and BlazBlue.
