Lil Nas X will need to see off the challenge of a sea shanty to secure a second straight week atop the U.K. singles chart.

The U.S. rapper’s “Montero (Call Me By Your Name)” is out front in the early stages of the chart week, though not by much.

“Montero” leads the First Look chart, which gauges the popularity of singles based on sales and streams after the first 48 hours, with Nathan Evans’ “Wellerman” just 500 chart sales behind in second place.

Riton x Nightcrawlers’ “Friday” featuring Mufasa & Hypeman is another 700 chart sales behind at No. 3, according to the OCC, and is still very much in the race.

Joel Corry, Raye and David Guetta could snag a spot in this week’s Top 5, as “BED” lifts 7-5 (up 19-13), while new releases from Ava Max (“My Head & My Heart”) and the Bruno Mars and Anderson .Paak project Silk Sonic (“Leave The Door Open” up 23-17) make their moves for a Top 20 spot.

The Official U.K. Singles Chart is published Friday evening, local time.
