Plus, 'Post Malone' (song, not artist) goes top 10.

Marshmello's Joytime III ascends 4-1 on Billboard's Top Dance/Electronic Albums chart (dated July 20) with 11,000 equivalent album units earned in its first full tracking week (July 5-11), according to Nielsen Music.

The set, released July 3, is Marshmello's third No. 1, following Marshmello: Fortnite Extended Set, for 16 weeks beginning in February, and Joytime II (one week, July 2018). The original Joytime hit No. 5 in 2016.

With 1,000 copies sold, Joytime III also earns the top spot on the Dance/Electronic Album Sales chart (2-1).

Concurrently, Marshmello charts a personal-best 12 tracks simultaneously on Hot Dance/Electronic Songs, including Joytime III's "Proud," which finds the DJ singing (No. 14). Marshmello, whose "Happier," with Bastille, logs a record-extending 43rd week at No. 1, debuts eight entries, upping his career count to 37, as he ties Calvin Harris for the third-most in the chart's six-plus year history; Avicii leads with 42, followed by David Guetta with 41.

PARTYING LIKE A ROCKSTAR: As Post Malone debuts at No. 3 on the Billboard Hot 100 with "Goodbyes," Sam Feldt surges 14-10 on Hot Dance/Electronic Songs with his track "Post Malone," featuring RANI.

The first Hot Dance/Electronic Songs top 10 for both acts shouts out its namesake act: "Tonight, we go all night long / We party like Post Malone!"

GOOD 'MEDICINE': Jennifer Lopez and French Montana top Dance Club Songs with "Medicine." J. Lo's 17th leader (and Montana's first) ties her with Mariah Carey and Kristine W for the sixth-most No. 1s all-time; Madonna (new at No. 26 on the chart with "I Rise") leads with 47.

"Medicine" was remixed by Kaskade, Eric Kupper and Metromix, among others.
