Reality is charts not fit for purpose with the streaming era. I agree they're too convoluted to matter too much
However I will say if you want it to be what the most popular songs on streaming, there's nothing stopping you from just looking at those streaming charts yourself
If you care too much bout billboard for Stan purposes that's a you problem - not that OP does, it's a fair op, but a lot of people on here always crying bout how radio counts and s*** if it keeping one of their faves from no. 1.
To keep the charts interesting they prolly do actually need even more rules like the UK ones I mentioned. Just the debate of whether keeping them interesting is worth even more convolution
