I have tried a both a 15-minute &quot;quick relax&quot; session and a full 8-hour sleep session. Based on the &quot;quick relax&quot; session, I assumed this music was based primarily on binaural beats (hence the need for headphones), but the sleep session didn&#x27;t seem to use the beats as strongly (if at all). I have trouble sleeping at night due to both stress and restless leg syndrome, and while this music didn&#x27;t put me to sleep right away (and the headphones definitely didn&#x27;t help), I do think I was better off last night with the music than without.<p>I would be willing to pay for this, but the current price is too high. I think about $24&#x2F;year would be something I could justify (but still not an impulse buy). I listen to a lot of DJ mixes for free on Youtube&#x2F;Mixcloud and buy a few tracks a month to support the producers I like. If I were to add your service as well, that would more than double my cost of music.
