Charlie Harding and Nate Sloan

So it's not a sound you get to hear very often, much less in the middle of a BTS album.

It's a palate cleanser.

It's another reference to Korean heritage.

And it kind of signals a transitional moment in the album.

If the opening tracks have all been mainly hip-hop in style, after this bell ring, we're going to move more into the world of pop and ballads and melody-forward music.

including the biggest hit and the lead single from this album, Swim.

Like a lot of contemporary pop songs, it starts with the chorus here sung by Jungkook and Jimin.

And unlike anything we've heard so far, this song is entirely in English.

Also, those Korean references that we've been detecting throughout, I'm not sure we're going to get any here.

This is a different side of BTS and maybe one that is reaching more for that Western global market.

It feels almost like a chorus by The Weeknd.

Dark, melancholy, melodic, you know, nods to hip hop and R&B, but really slow.

I had a similar reaction, maybe more leaning towards Frank Ocean, who has a song called Swim Good.

I mean, BTS have excellent taste.

Something that is exemplified by the producer they bring in for the next track, Merry Go Round.

I'll play this one and then Charlie will put you to the test and see if you can name the ringer they brought in for Merry Go Round.

I have not looked it up.

I'm coming in.

No knowledge.

Sometimes when you bring me something, the less I know, the better.
