In one of the closest races, Psy's "Gangnam Style" was edged out once again by Maroon 5's "One More Night" for the top spot on Billboard's Hot 100 Chart.

Billboard's Gary Trust wrote,

The race was extremely close. "Night" bests "Style" by fewer than 500 overall chart points, after "Night" won last week by approximately 3,000 points. (This week's points difference between Nos. 1 and 2 is the thinnest, in fact, since the Feb. 18 chart.) Both titles gain in overall points this week, but "Style" closes the gap courtesy of an 8% overall points gain, while "Night" increased by less than 1%.

Key to Maroon 5 maintaining its lead? Radio airplay. "Night" remains at the Hot 100 summit with top Airplay Gainer honors for a fifth consecutive week, as it holds at No. 2 in its 10th week on the Radio Songs chart with a 15% increase to 116 million all-format audience impressions, according to Nielsen BDS. The radio run of "Style" is in its early stages, so it doesn't boast the stratospheric audience level of "Night." Still, "Style" surges by 37% to 46 million, pushing 34-23 on Radio Songs.

The greatest victory for "Style" over "Night" this week is in digital sales. Despite a 2% decline to 294,000 downloads sold, according to Nielsen SoundScan, "Style," which dips 1-2 on the Digital Songs chart, outranks "Night," which drops 2-4 with a 12% decrease to 181,000.

So although "Gangnam Style" has a big lead in downloads, "One More Night" stays on top for one more week mainly because of radio airplay.

It'll be interesting to see if Psy will perform shirtless even though he didn't reach #1 for his October 4th concert.
