I found the intense focus music (and the &quot;white noise&quot;&#x2F;hissing in it) to be really, really grating and kinda put me on-edge while listening.<p>I also found the repetitiveness&#x2F;predictability of the rhythm to be troubling - I&#x27;d end up focusing on the noise and thinking about &quot;what was coming next&quot; to be ultra-distracting.<p>Kinda like when you have a noisy neighbor at night and you are just trying to get to sleep, but all you can focus on is the noise coming from your neighbor.  You cant switch off - all you can do is focus on the noise.<p>Personally nothing beats rainymood.com for focus for me, but thanks for sharing.  I guess I am different as everyone else seems to think this is effective.
