Go add up their daily averages and multiply it by 365. If Taylor is past her prime why was Red the biggest female album debut on Spotify ever? In what metrics is Madonna increasing, in a way that would significantly counter Taylor’s 56% YOY growth in Spotify streams (5.9B in 2020 and 9.2B in 2021, which btw is equivalent to 9.2m CSPSC for 2021 just from audio). Additionally, every indication is that in the streaming era recurrent streams don’t just disappear, they stabilize and then grow over time as platforms grow, so it’s hard to see Taylor collapsing that far anytime soon.

I think fans are unable to realise that CSPC is an own derived analysis and not a industry written rule, a lot of countries does not even have SPS to begin with especially Asian countries a lot of other countries have paid vs free streams while YouTube views accounting only happens in 2-3 countries.
It's an analysis not a measurement who is outselling who which seems to be your concern - there is a reason why IFPI don't have any Worldwide SPS to account for because with that every country has to join hands with IFPI and provide a method which is not possible.

I think Taylor overtakes Barbra some day. But I think is hard she overtakes Whitney, Mariah, Celine and especially Madonna.

I think that her outselling Barbra and Whitney is inevitable considering she'll only be 20m behind both of them by the end of this year (she's eyeing for 125m believe it or not)
her pushing higher depends on her next releases, her selling power is still insanely high but what her last few releases truly lacked is a huge smash hit, they all had moderate hits to underwhelming singles under their belts which is somewhat keeping them behind her her first 5 albums.
if her next studio album manages to get a smash hit à la "I Don't Wanna Live Forever" and a few more mid sized hits whilst retaining her album selling appeal she'll definitely have a blockbuster era. but this is all an "IF" for now.

so basically in my opinion she's gonna end up anove Barbra and Whitney no matter what, she'll challenge Mariah and potentially Céline but I do think Madonna is too far ahead.

i don't understand why the interpretation of the metric matters? Like the original disagreement seems to be about whether Taylor will acquire more CSPSC than Madonna, if your original comment meant outsell in terms of documented ifpi/label reported sales, then we will never know so it seems unnecessary to even bring that into the conversation.

That's not necessarily true. The beauty of the streaming era is having a smash hit isn't necessary to drive album sales like it used to be. Recurrent streams are far more indicative of who will pull ahead of who in the long run. To say Taylor won't garner more CSPSC ever seems misguided because if you look at the recurrent Spotify daily numbers, Taylor's would either need to collapse by 90% or Madonna's will have to increase tenfold. Not to mention the millions of pure Taylor is moving yearly.

If anything the lack of the need for a smash hit can be seen by Enchanted (2010 album track) gaining more daily streams than some of the biggest smash hits of the past couple years (Bad guy, rockstar, Senorita, etc.).

Sorry to say but 2021 was Taylor biggest consumtion year ever in US (I don’t have data ww but may too). Her albums are less bigger than 1989, Red or Fearless but everything in her discography is selling well and her re-recordings are smashing

Yeah, I wuold say that Taylor maybe is one of the few or only actual artist that not need a smash popular hit for been in the top and gained massive sales, thanks to his very strong catalogue that her build and the big powerful fan group she have.

I did not write that comment. My account was hacked or its a different account. You can see by the way I write. I have no idea who wrote that.

But back to the original question, Taylor is not moving millions of pure sales. She doesn't have hits at the moment, and while her streams are very good, I think she'll end up above Mariah, and she will challenge Celine.

Madonna though, is a very special case. She has been producing blockbusters 25 years into her career. I don't know if Taylor can do it. It's a big IF as someone else said here.

If she gets very successful albums later on, I may change my mind, but at the moment, she doesn't have a chance in my opinion as her old catalogue alone won't get her near Madonna, regardless of how well it sells.

I am a different person.

I just wanted to make things clear as fans are thinking CSPC units is official it's website one method for analysis on which they work very hard.

IFPI is starting to go in the same direction as they released their newly released global album all format chart last year. Annual Global Recording Artist is also determined based on total equivalent album units.

In relation to Taylor possibly surpassing Madonna, the future is uncertain, she may or may not do it. But if you will ask me, I don't think she will. Taylor already reached her peak. Her sales are declining. What's giving her million of units now is her consistent release of albums annually. If anything, her having to re-record her past albums is a blessing. It allows her to break chart records, boost her streams, and shift more units every year.

In 2021 Taylor sold 725k+ pure sales in China (which count fully via the new Chinese pure methodology for CSPSC), and moved 1.77m pure in the US from just her 4 albums albums that cleared the top 50 YTD units (Via Hits DD YTD Overall Activity). Taylor likely very easily crossed 3m global pure sales for 2021. She doesn't have a strong smash at the moment but again when your back catalogue does over 20k CSPSC daily from audio streams alone (excl Red TV), having hits wouldn't change the end result just speed it up.

She sells digital copies in China.
This is not the same as selling physical albums.

I am not denying that what I am trying to say is that CSPC formula is not official it's their own analysis giving the popularity of an album IFPI doesn't give you global SPS because there is no way of calculating my point still stands on this.
11475 YT views = 1 album unit is website's own analysis and nothing else. Taylor is not going anywhere and she will continue to move and sale albums but CSPC is a own derived method it doesn't mean it's 'outselling' other artist.

IFPI is starting to move is another point, it is impossible for every country to come under IFPI counter especially Asian countries there are free members vs paid members it will become very complicated for IFPI to calculate all this though anything can happen but I don't see it.
