BTS, the Korean K Pop Dynamos, have set a record for at least the recent modern past.
Sony Music claims that BTS’s single “Butter”, currently number 1 or 2 everywhere, represents the first time that an international group has debuted on all Top 40 stations at once.
This is probably partially true. In the 60s, there was no top 40 measure like there is today. The Beatles, an international group, commanded the top 40 in 1964 and 1965. Within a week, they occupied the top 5 places on the charts and many other positions. There wasn’t a station in the United States that didn’t broadcast their music all day, every day.
But let’s say since 1990 or even 1980, BTS now has that distinction. The “butter” is hot and melts on everything. It’s a perfect pop top 40 hit, full of energy and absolutely immemorable. But the BTS machine was built at that time, so we’ll let them have it.
