Well yes. Music Box Cassette: $10.98 CD: $15.98 Average unit price in 1993: $13.48 For reported sales, the common conservative figure is over 28 million worldwide for Music Box. Some sources claim 30M+, but lets use 28M as the safer base. Estimated gross revenue at 1993 prices 28,000,000 copies × $13.48 = $377,440,000 So, at the average cassette/CD list price, Music Box would gross about: $377.4 million in 1993 dollars. Inflation-adjusted to 2026 Cassette today: about $25.14 CD today: about $36.58 Average today: $30.86 28,000,000 copies × $30.86 = $864,080,000 in 2026 dollars. That's just for one album for one act. If you add up all of the album and single sales and adjust for inflation, this outgrosses even Taylor (even if you include her tours). Taylor would need 172B streams on Spotify to equal one Mariah album in revenue. The money flowed greater back then thus less need for touring. If you add up both tour, single sales, album sales and adjusted for inflation, Mariah made more in 1990s if you compare it Taylor's 2020s touring, sales, and streams. And to address the rest of your argument. A modern album-equivalent unit is an accounting/chart conversion, not a customer handing somebody $15. IFPI explicitly says that streaming, downloads and physical formats are converted into a common global chart figure using economic weighting. Physical sales themselves are actual units; streaming "units" are converted from streams according to a methodology. So an "equivalent album" assembled out of 1,000–3,000+ streams does not magically become the economic equivalent of somebody walking into Tower Records in 1994 and paying $14 for an album. Mariah's 1990s album business generated consumer spending comparable to or greater than the entire Eras Tour after adjusting for inflation. And that is before Mariah's enormous physical-single business. Sony said she had already sold more than 80 million records by Butterfly in 1997. This fact alone generates more revenue than both Taylor's 2020 reported pure sales, touring revenue, and Spotify streams even when you add them all together. Continuing onward. There's also broader industry data backing up my statement that recorded music itself carried considerably more economic weight during the physical era. Congressional Research Service analysis of RIAA data puts U.S. recorded-music revenue at its inflation-adjusted peak of $25.6 billion in 1999, in 2024 dollars. To make my point clearer for anyone reading in comparison, 2024 U.S. recorded-music revenue was $17.7 billion at estimated retail value despite today's vastly larger quantity of music consumption. Overall your "$2.5 billion" rebuttal does not actually answer my argument, because you are taking modern consumption-equivalent units and treating them financially like full-price physical record purchases.
