On the final day of Sleepy April What other file could it have been?
The file doesn't really need a summary or a target audience or any official explanation, it's just a short, gentle file to help you fall asleep as you listen to it. A short file to get rid of the stress and worries of the day and help you sleep like a baby, like a kid who didn't worry about his job or his studies, just a file to use whenever you need help to sleep.
So, listen. Listen and enjoy and let my voice help you sleep!
