Taylor Swift’s Rerecording of ’1989’ May Be Her Biggest Yet. Here’s Why.

Swift’s world tour, which has played to packed stadiums since March and is in line to sell well over $1 billion in tickets by the time it ends next year, has generally lifted her entire catalog. At various times this year, at least 10 of her albums, including the originals, have been in the Billboard 200, the magazine’s flagship albums chart.

But each time Swift has released a rerecorded album, its corresponding original version has suffered. In the year after she released “Fearless (Taylor’s Version),” sales of the original fell 20 percent in the United States, according to Luminate, the tracking service that supplies the data for Billboard’s charts; the original “Red” dropped by about 45 percent. Neither has been on the Billboard 200 since 2021.

Jaime Marconette, Luminate’s senior director of music insights and industry relations, noted how stark that impact can be on a week-to-week basis. In May, Swift said she would release a new “Speak Now” in eight weeks. “That announcement,” Marconette said, “immediately drove a 75.7 percent increase in total consumption for the original version.” But as soon as “Speak Now (Taylor’s Version)” came out, the original sank. Comparing a window of 14 weeks before and after the new version, the original fell 59 percent.

On the latest chart, the new “Speak Now” is No. 18. The old version, which was most recently No. 191, had fallen off the chart entirely.

Statistics like that call into question the value of Shamrock’s investment, which has been estimated at more than $300 million. In the short term, at least, there is no doubt that Swift’s rerecordings have severely dimmed the originals. But it may take years before it is clear whether there is a lasting impact. A spokeswoman for Shamrock said that no one at the firm was available to discuss the matter.

Swift also stands to earn more money from her new recordings than her old ones, thanks to a deal she negotiated with Universal Music, Republic’s parent company, that gave her ownership rights to her recordings.
