It already is in over half a dozen other countries, the US is a bit slow I guess.
Still 300K actual to go or there abouts. funny she used to move that in less than a week.... and sales are dropping every week at the moment (26K @ week 77)... .hopefully get there before years end or less than two years. Which is a big deal when you consider many other albums that have gone diamond recently have taken a decade to sell 10 million actual...
When it reaches diamond, Im sure it will be the fastest to reach diamond right?
Based on its historic momentum It could well hit 24 million WW before it goes diamond in the US. Making it, according to Media traffic, one of the top 40 album's ever WW in less than two years....a 21st century album up there with the likes of Nirvana's, "Nevermind" and Metallica's Black album
Actually no, The Beatles, and Nsync are an example, The latter sold 8 million in one year.
21 passed 8 million actual ( vs shipped) in its 55th week...so not far off the pace.. it was 9 million by week 64 and we're currently around the 9.7 million mark at week 77 ....The last million is definately the slowest.... The good news for Adele fans is that it looks like 21 may scrape in for 78 consecutive weeks in the top 10......thats 18 consecutive months in the top 10
The current no.2 slot, Adele's '21', which sold 85.000 copies in its 81st week on the tally. The total sales of '21' break through the 23 million border this week.
in less than two years
The good news for Adele fans is that it looks like 21 may scrape in for 78 consecutive weeks in the top 10......thats 18 consecutive months in the top 10
