I fully acknowledge that, to the best of my knowledge, no one has tried to sleep better by congregating with thousands of similarly-sleep-seeking others into a jam-packed stadium. I will also point out that, again to the best of my knowledge, extremely little money is made by the music industry on sleeping pills, sleeping hardware (beds, mattresses, pillows) and necessities (covers, duvets), nor on specialised sleeping gear (masks, blinders, apneu machines). Also: most people try to or need to sleep every night, but can go without a concert for multiple days. If you can sell something on a recurring basis, you don't need to make a ton of profit on each sale to get a nice income stream. Finally: I think it is harder to improve the sleep of someone struggling with that, than to create entertaining music.
