I was doom-scrolling the Billboard World Albums chart update on a Saturday night, mostly to check on Stray Kids’ new “THIS & THAT” (No. 1, obviously), when line 21 stopped me cold: BTS’s “Love Yourself: Tear.” An album from 2018. Sitting at No. 21. In its 220th week on the chart. Not a typo. So here’s your FAQ, because I had questions and you probably will too.
Wait, is the Billboard World Albums chart glitching?
Not a glitch — this is just how the Billboard World Albums chart works, and it runs on different math than the Billboard 200. It ranks any non-US artist by album-equivalent units, a blend of physical sales, digital sales, and streams. Billboard actually tightened its streaming formula in January 2026, making it slightly easier for old albums to keep racking up units.
But the real answer is K-pop’s fandom economy runs on different rails than Western pop. Labels keep issuing photobook reissues, anniversary repackages, and fan-club exclusive variants of old albums for years, and completionist fans buy every version while also streaming full back catalogs. That’s how an album survives on a sales-based chart in a way a 2018 Ed Sheeran record just doesn’t in 2026.
Why is it happening this specific week?
Timing. All seven BTS members spent 2023-2025 on mandatory Korean military service, finishing up between April and June 2025, then reunited for “BTS The Comeback Live: Arirang” in March 2026 — their first full-group show since 2022. That reunion sent fans back through the whole catalog, which is exactly what reignites streaming and repackage-hunting for “Love Yourself: Tear” and 2022’s “Proof” (also charting, at No. 4, in its own 218th week). For comparison, “Map of the Soul: 7 ~The Journey~” sits at No. 11 in week 41 — solid, but nowhere near 220.
What about NewJeans? Aren’t they in legal trouble?
That’s the wildest data point here. NewJeans’ 2023 “Get Up” is at No. 15 in its 153rd week — nearly three years — despite the group spending 2025-2026 in a messy court battle with label ADOR over creative control. A Seoul court ruled against them in October 2025, binding them to their contract through 2029; the members paused activities entirely in May, and member Danielle has since left. A group that’s released almost nothing new in over a year is still moving units off an old EP. That’s fandom purchasing fully decoupled from new content — not really a thing for a quiet Western pop act.
Does this happen to newer groups too?
Already starting with CORTIS, Big Hit Music’s newest act (debuted August 2025, after BTS and TXT). Their debut EP “Color Outside the Lines” sits at No. 7 in its 49th week, while their newer “GREENGREEN” is already at No. 2 in week 15 — two simultaneously charting projects before their first anniversary. That’s the built-in older-sibling fanbase effect of debuting under a BTS-adjacent label: it compresses years of catalog-building into months.
What’s the full picture?
The real numbers, side by side:
Notice the gap: new releases fade normally through week 41, then CORTIS (49 weeks) and NewJeans (153 weeks) form a middle tier propped up by circumstances that have nothing to do with new music, and BTS’s own catalog sits alone at 218 and 220.
Why should I care if I’m not a superfan?
Because it’s a clean, verifiable window into how differently K-pop’s fan economy runs. In the US, a chart run usually measures “is this still popular right now.” In K-pop, it’s closer to measuring the size and loyalty of a fandom’s spending habit, which can stay high long after the cultural conversation moves on. It’s also a good signal for what BTS’s reunion actually means commercially — their old catalog isn’t just surviving the hiatus, it’s still selling, which bodes well for whatever new album drops later this year. And if you needed a reason to feel something about NewJeans: their fans are still paying for an artist their own label won’t let make new work.
