Please bring us Deep Purple's sales data. It would be difficult but Purple is a immense legend for hard rock/metal/prog fans.

I agree Rodolfo, I love Purple, they should and will be analysed. I will help it happen.

if RiAA isn’t on top of VHs album sales where are u getting ur figures ? thx

what the heck is ORPHAN?? I read entire article and did not find it. Please explain.

Orphan are the songs that aren't part of any studio album.

How accurate are the numbers considering a lot of VH's album's haven't been recertified by the RIAA in almost two decades. Is this info current, or are you going by what has been certified to this point?

The certifications are taken into account but the sales totals are estimated up to the point of the article.

We are long long overdue on a Rush update. 95% of their catalog hasn't been recertified since the 80s and 90s. Please do a Rush one ASAP. Amazing work on VH.

I love how you used the word "mammoth" to describe one of their record sales. As a fan since 1980, I immediately caught that. 🤩 Thank you for this interesting and in depth analysis of VH albums, singles, orphans, etc.
