While the top two songs in the country remain unchanged from last week, other acts saw their songs climb or hit a previously unreached mark on the charts.

Robin Thicke's "Blurred Lines" and Katy Perry's "Roar" remain No. 1 and No. 2, respectively, but Imagine Dragons' "Radioactive" is sitting at No. 5 after a year (52 weeks exactly) on the Billboard Hot 100. In fact, it's so rare for a song to be in the top five after a year on the tally that only one other song has done so: Adele's "Rolling in the Deep."

With 175,000 copies sold this past week, Avicii and Aloe Blacc's "Wake Me Up" enters the top 10 at No. 7 (at No. 3 on the Digital Songs chart). It's the first time either act has seen their work in the top rankings.

Having previously entered the top 10, Capital Cities' "Safe and Sound" climbs even higher this week to finish at No. 8, giving the song and the band their highest mark to date on the chart.

Lana Del Rey and Cedric Gervais are also celebrating their first Hot 100 top 10 placements, as the remix of "Summertime Sadness" (originally a slower track by the latter artist) jumps to No. 9. It sold 132,000 copies this past week.

Rounding out the top 10 is Daft Punk's "Get Lucky," featuring Pharrell.
