Netflix's Stranger Things finale, which dropped Dec. 31, is shaking up the Billboard Hot 100.

The holidays are over, both on the calendar and on the pop charts, and that's great news for an assortment of beneficiaries.

Billboard has revised its system of removing songs from the Hot 100 singles chart once they've gotten too old to qualify as contemporary hits.

This week's albums and singles charts are both dominated by the same record: Sabrina Carpenter's Man's Best Friend, which debuts at No. 1 and lands all 12 of its songs in the Hot 100's top 40.

A K-pop blockbuster lands atop this week's Billboard albums chart, but it's not the one you might be expecting.

This week, Morgan Wallen's I'm the Problem sits at No. 1 on the Billboard 200 albums chart again. But the two titles just below it are making the most noise: Conan Gray's Wishbone and KPop Demon Hunters, which pulls off something no soundtrack has ever accomplished.

The KPop Demon Hunters soundtrack just placed three songs in the top 10 of the Hot 100 charts simultaneously — a feat not many movie soundtracks have accomplished.

The members of HUNTR/X — the fictional K-pop group made up of nonfictional singers EJAE, Audrey Nuna and REI AMI — have just become the first women K-pop artists ever to hit No. 1.

The idea that each year produces a few unofficial "songs of the summer" has been rattling around for ages. But do we have a strong contender this year?

This week on the Billboard albums chart, Tyler, The Creator's Don't Tap the Glass charts at No. 1 and Ozzy Osbourne's The Essential Ozzy Osbourne races to No. 7 in the aftermath of the singer's death.

It's a slow week on the Billboard charts, but a few albums and singles are still having a huge impact, including Drake's new single, "What Did I Miss?," and the soundtrack to the Netflix original movie KPop Demon Hunters.

This week's highest debuts on the Billboard 200 albums chart — Benson Boone's American Heart, Karol G's Tropicoqueta and the soundtrack to Netflix's KPop Demon Hunters — all land in the top 10. But they don't come anywhere near displacing Morgan Wallen's I'm the Problem.

For the fifth consecutive week, Morgan Wallen's I'm the Problem tops the Billboard 200 albums chart. But there's plenty of volatility beneath him on the chart.

"Manchild," the first single from Sabrina Carpenter's forthcoming album Man's Best Friend, enters this week's Hot 100 singles chart at No. 1, making a late-breaking bid for "song of the summer" status in the process.

Morgan Wallen's I'm the Problem continues to dominate the charts, while long-ago chart queen Connie Francis is gathering momentum for a song from 1962.
