As previously reported, The Weeknd remains at No. 1 on the Billboard Hot 100 (dated Oct. 10), as "The Hills" spends a second week on top and becomes the best-selling and most-heard song in the U.S. Meanwhile, Drake surges into the Hot 100's top five with "Hotline Bling" and ups his career total to a milestone 100 entries. Plus, Taylor Swift reaches the top 10 with "Wildest Dreams."

Who else makes noteworthy chart moves?

Shawn Mendes, "Stitches"

Mendes' highest-charting Hot 100 hit moves within a notch of the top 10 (12-11). It gains across the board, holding at No. 13 on Streaming Songs (8.8 million U.S. streams, up 8 percent, according to Nielsen Music) and lifting 9-7 on Digital Songs (75,000 downloads sold, up 1 percent) and 20-15 on Radio Songs (60 million in audience, up 19 percent). Mendes additionally earns an impressive first: his first top 10 on a U.S. airplay chart, as "Stitches" climbs 11-10 on Pop Songs.

Mini-"Ask Billboard" time! Mark Ronson and Bruno Mars are in anything but a funk:

'UPTOWN FUNK!' MOVES BACK UPTOWN

Hi Gary,

Any thoughts as to what caused "Uptown Funk!" to surge from No. 27 to No. 14 after nearly a year on the Hot 100? I can't recall the last time I saw anything quite like this on the chart.

Hi David,

"Funk" flies back up as the Hot 100's top Streaming Gainer, bounding 22-9 on Streaming Songs, up by 81 percent to 10.2 million. Of its streaming total, a hefty 58 percent is from non-Vevo on YouTube clicks, driven in large part by the user-generated clip above, which has recently gone viral on Facebook and Twitter.

Meanwhile, the former 14-week Hot 100 No. 1 tallies a 42nd week in the top 20. Only one single has spent more time in the region: Jewel's double-sided "You Were Meant for Me"/"Foolish Games" (46 weeks, 1997). LMFAO's' "Party Rock Anthem," featuring Lauren Bennett and GoonRock, ranks third with 40 top 20 weeks (2011-12).

The Hot 100's top debut at No. 22 also bows at No. 5 on Digital Songs (78,000) and No. 44 on Streaming Songs (4.6 million). The cut is the lead single from Goulding's Nov. 6 album Delirium.

Other noteworthy pop songs debuting on the Hot 100 this week: One Direction's "Infinity" (No. 54), Demi Lovato's "Confident" (No. 84), Naughty Boy's "Runnin' (Lose It All)," featuring Beyonce and Arrow Benjamin (No. 90), Major Lazer's "Powerful," featuring Goulding and Tarrus Riley (No. 95), and A Great Big World's "We Hold Each Other," featuring Futuristic (No. 99).

Calvin Harris & Disciples, "How Deep Is Your Love"

Harris notches his ninth top 40 Hot 100 hit, and Disciples its first (46-39). The collab holds at No. 37 on Streaming Songs (4.5 million, up 3 percent) and surges by 27 percent to 27 million in radio audience. UPDATED: As eagle-eyed commenters wondered below, how could Harris' "Deep" rank at No. 37 on Streaming Songs with 4.5 million and Goulding's "Mind" rank lower, at No. 44, with a higher sum (4.6 million)? All those numbers are correct; however, the streams are raw totals; types of streams (i.e, programmed vs. on-demand) are weighted differently, under the Streaming Songs chart's formula, resulting in the higher overall rank on the chart for "Deep." It's similar to how plays are weighted on an audience-based airplay chart, like Radio Songs, whereby, say, a play in morning drive in New York counts significantly more than 10 plays overnight in a much smaller market.

Harris' hit marks the third different "How Deep Is Your Love" to reach the Hot 100's top 40: the Bee Gees' love song reigned for three weeks in 1977-78 and Dru Hill's Redman-assisted track hit No. 3 in 1998.

Keith Urban, "John Cougar, John Deere, John 3:16"

John (formerly Cougar) Mellencamp is back in the Hot 100's top 40, via Urban's name-check at least. The song pushes 41-40 (and holds at its No. 2 high on Hot Country Songs), granting Urban his 17th top 40 visit. Mellencamp has managed 22 top 40 hits (not counting this ode), between 1979's "I Need a Lover" and 1996's "Key West Intermezzo (I Saw You First)."

(Meanwhile, "John Deere" makes his/its first top 40 trip. The equipment company, formed by its namesake in 1837, tallied one prior Hot 100 appearance: Joe Diffie's "John Deere Green" motored to No. 69, and No. 5 on Hot Country Songs, in 1994.)
