On December 15, Fall Out boy released a new version of “Champion” featuring RM of K-pop group BTS.

Based on activity generated during its first full week in the market**, “Champion (featuring RM)” earns a spot on this week’s Billboard Bubbling Under Hot 100.

“Champion” takes #18 on the listing, which lists the Top 25 songs that have yet to appear on the actual Hot 100.

Adhering to the same formula as the Hot 100, the Bubbling Under chart ranks songs based on combined activity from sales, streams and radio airplay.

Radio was a non-factor for “Champion” this week; its Bubbling Under position is attributable to sales and streams.

“Champion” fared particularly well from a sales standpoint, earning #23 on this week’s Billboard Digital Song Sales Chart.

**Editor’s Note: While the RM version generated the overwhelming majority of this week’s sales and streams, the chart position technically includes activity from the original version as well.
