There's not a lot of movement this week on charts, but if you look closely, there are some gems.

As Billboard reports, Miley Cyrus' "Wrecking Ball" and Katy Perry's "Roar" remain Nos. 1 and 2, respectively, although the latter saw more gains and has now topped the Radio Songs chart. Meanwhile, Lorde's "Royals stays at No. 3, leaving the top three unchanged from last week. However, "Royals" saw a big leap in sales, climbing from No. 3 to No. 1 with 307,000 copies sold.

The news comes as 16-year-old Lorde prepares to release her debut album, Pure Heroine, which arrives on Sept. 30. But as she tweeted last week when her song reached No. 1 on iTunes, the win was bittersweet, considering the hateful comments from fans of Cyrus.

The young singer also maintains the No. 1 spot on the Alternative Songs chart for a seventh consecutive week, after breaking the record two weeks ago for the longest-running No. 1 by a female artist.

Avicii's Aloe Blacc-assisted "Wake Me Up!" also gained this week, moving 5-4 on the Hot 100, up by 12% in streaming and 15% in airplay. It is currently the No. 1 track on the Dance/Electronic Songs chart.

Elsewhere on the chart, Drake's "Hold On, We're Going Home," featuring Majid Jordan, hit a new high at No. 7 with double-digit gains in both airplay and streaming and 150,000 copies sold.
