This could be a beat
Everybody is gonna post the goats, from Sonic down to the impeccable Streets of Rage 2 soundtrack, but Donkey Kong Country had some of the most....ambient shyt I've ever heard from a videogame. I remember as a kid I used to just load up the stages and leave the game run just to listen to this shyt.
Also, this little unknown gem for the original Xbox had a pretty solid soundtrack that rival's most anything you'd hear today. This track alone, had me hopping, much less EVERY fukking stage you went to where the music changed to some pretty groove, down delta shyt. It's available on XboxOne so you have no excuse in missing out on such a kick ass platformer if you're into that sort.
