It's just a marketing term now, used fast and loose. It's getting close to undermining any true meaning conpletely
I do think it's interesting that it's become a style that is adopted by new bands some in an almost "by numbers" approach which can lead to varying degrees of contrivance and success.
Some examples I can get along with well, others drive me screaming away
Try Web Web as an example of this, it's as if they've ticked every 'Spiritual Jazz' box.

I regard this as a better example, your view may differ
