"Uptown Funk" is going to continue to give it to ya, and it looks like Mark Ronson and Bruno Mars are going to be topping the charts for quite some time in 2015. After finally outing Taylor Swift from the No. 1 spot in the U.S. last week, for the second week in a row, Ronson's funk-infused lead single from his new album Uptown Special crowns the Billboard Hot 100.

Ronson and Mars's "Uptown Funk" owns the charts yet again this week thanks to a key blend of sales, streams and radio play. "Uptown Funk" - which was one of Music Times's favorite songs of 2014 - was the top-selling digital download of the week, moving 341,000 copies. The song also dominated the Streaming Songs chart with 11.6 million plays and had a solid showing on radio with 103 million audience impressions.

Billboard notes that "Uptown Funk" is in for a long, comfy time at No. 1. The single's album Uptown Special dropped on Tuesday (Jan. 20) and is only set to add to the track's chart points in the coming weeks.

The top four songs in the country remain the same this week, with Taylor Swift's former No. 1 single "Blank Space" holding steady at No. 2. She leads the rest of the stagnant top four, with Hozier's "Take Me to Church" and Ed Sheeran's "Thinking Out Loud" holding at Nos. 3 and 4, respectively.

A minor shake up happened in the top five; Sam Smith's latest In The Lonely Hour single "I'm Not the Only One" re-entered the top five to its No. 5 peak.

The bottom half all sounds very familiar to fans who follow the charts. Meghan Trainor's second Title single "Lips Are Movin'" fell one spot to No. 6. She's succeeded by Nick Jonas's "Jealous" at No. 7 and Swift's "Shake It Off" at No. 9.

Between Jonas and Swift, Ariana Grande and The Weeknd's "Love Me Harder" re-entered the top 10 this week, climbing three spots to No. 8.

The top 10 is rounded out by Trainor's lead Title single "All About That Bass," bumping Maroon 5's "Animals" from the charts, just in time for the band's latest V single "Sugar."
