90 seconds 😆 wait until 90 minutes 😂😂😂

It's all 'subtle' 😉

I can tell you, the first 10 minutes is goosebumps time from A to Z for me 😉 More of those bumps when listening with my headphones, rather than through my laptop speakers. 100% focus and closed eyes add to the bumps amplitude (or heights). Eyes open and executing some other task, like writing this comment, reduces those effects 😉 {yes, listening to the opening of the same recording right now 😉}
