My faves better stay in the top10 so I can continue to track them
They usually leave the top10 due to new releases then bounce back.
I love MusicCharts and how inflated their numbers are but they are not reliable at all. Their numbers are usually higher than what IFPI reports at the end of the year.
So now, we only need to wait for IFPI to publish their reports to get accurate sales.
An alternative would be to track certifications but most of them now incorporate streaming, so it's messy
