I don’t think they’ve fallen off at all - I think their releases are just thematically a bit divisive. Personally, I love that- think it’s good they’re not resting on their laurels and are keeping things interesting. But I understand there is a certain demographic that wants acts to find their sound and stick to it.
Personally, as a fan, I feel like I see growth, and also don’t particularly care about home turf results. Actually…, I don’t really care about global results! I only care about if enjoy it!
