Drift down, stay down. Sleep tracks slow gradually and avoid sudden dynamic shifts, so nothing in the mix wakes you up. They're designed to disappear into the room rather than end.
Long, slowing tracks for the first 20–40 minutes of trying to settle down.
Hour-long beds that hold a low, even floor through the night without waking you.
Shorter Wake Gently tracks that lift you out of a 20-minute nap instead of jolting you up.
