So I need help with something guys; since the old Madonna reciepts thread was closed over a year ago, I was thinking of making a new one or having the mods reopen the old one. I have my own sales estimations (complete with Wikipedia data for some

) and I'd like to know if some of them are off, particularly the singles and videos. I think I underestimated a lot of singles and videos. (Note: when I could find an exact sales figure with an at least semi-reliable source, I used it. "Don't Tell Me" looks oddly high to me as well.)
