It might be weird featuring a track called "Sunday" on a Saturday, but the good vibes know no day, right?
Medasin is one of the names I've been seeing the most around the SoundCloud future beats community and there's a pretty solid reason for this. Besides his funky and pretty awesome illustration artworks, the young producer has some seriously spot-on beats.
Not sure what (if) he has samples something here, but either way - enjoy your weekend and that track.
