been listening to a "concentration" playlist on apple music lately. for work.
it's like having clonazepam pumped through the vent system. it's like "brave new world," i think that's where that happens.
definitely not great for every occasion, but many good ambient tracks there (plus a sprinkling of other genres so you don't fall asleep) to aid your focus when you need some long-sustained extreme calm.
can't copypaste the tracklist, just sharing here in case anyone needs a valium. it lasts 11 hours! and refreshes every 2 weeks.
