11 weeks! Mark Ronson's "Uptown Funk!," featuring Bruno Mars, rules the Billboard Hot 100 for another week.

"Uptown Funk!" is the only the 2nd no.1 song this year...the first was "Blank Space" of Taylor Swift.

Maroon 5's "Sugar" records its new highest position at no.2.

This week, Sam Smith's "Lay Me Down" featuring John Legend and Fetty Wap's "Trap Queen" enters into the top 10.

Sam Smith's new version of "Lay Me Down" featuring John Legend jumps to no.8. The two Grammy-winner artists teamed up for the ballad's new version in support of Red Nose Day, a biennial event in which British residents wear red clown noses to raise funds and awareness for those in need in the UK and around the world.



Another new entry this week is rapper Fetty Wap's "Trap Queen" at no.10.

The New Jersey-born Fetty Wap lost the use of his left eye as a child. He recently explained.  "When I was little, I got into a little accident and it gave me congenital glaucoma in both of my eyes. But, the doctors saved one, so I was blessed to have my vision."

These are this week's most popular current songs across all genres, ranked by radio airplay audience impressions and streaming activity data from online music sources. Songs are defined as current if they are newly-released titles, or songs receiving widespread airplay and/or sales activity for the first time.
