I love that you are digging even deeper on the problem! We say it is to “reduce stress”, but that is because that’s a simplified catchall that many people can relate to. You are totally right that stress a symptom. The real underlying cause is lack of awareness and peace within one's own self - the ability to separate from feelings of stress or overwhelm and not let them define you, but look at them more objectively and no longer have upsetting things ruin your day for example. The music has very strong BEATS, which give the mind something EVEN more concrete to focus on (the beat, the breathing pattern, and the teachers voice all serve as the object of attention, like a mantra) - so even though its loud, it does in fact make it easier to cultivate focus for people who find traditional objects of focus (e.g. "following the feeling of the breath") hard to anchor attention on. For anyone who finds silent meditation effective, we are so happy for them and they don't really need our new approach. What we are trying to do is create a new experience that resonates with people who are more drawn to upbeat styles so we can help more people unlock more peace and happiness.
You are terrifying and I am not being snarky. If you have done your market research on the perception of terms like “meditation” for exercise moms, you will choose the correct path.
