jarjarjr's "folgers crystals" is the best, lo-fi-est track you can find out there. The track screams "chill dude, it's Sunday" or... the original title of Eminem's track he flipped "Just don't give a fuck".
This is the first time I stumble upon the Irish producer/graphic design studen also known as "rap game isaac newton", but his SoundCloud is a real sound treasure. Now it's time to mellow out and smile stupidly at life.
