Two acts chart current rock hits in the top 10 simultaneously for the first time in two-and-a-half years.

With the ascent of Portugal. The Man's "Feel It Still" to the top 10 of the Billboard Hot 100 (jumping 14-10) on the latest chart (dated Oct. 7), the list houses two rock acts within its top 10.

Above "Feel," which marks the alternative rock act's first Hot 100 top 10 (in its first appearance on the chart at all), Imagine Dragons' "Believer" rises 9-7 in its 13th week in the top 10, having peaked at No. 4.

The last time two rock songs were in the Hot 100's top 10 isn't terribly long ago, but they were by the same act: twenty one pilots populated the bracket between the charts dated Aug. 27 and Oct. 1, 2016, with both "Ride" and "Heathens."

But before then, the last instance until this week in which rock songs by at least two acts infused the top 10 together? Try two-and-a-half years ago.

That's when, amid the rise of Hozier's "Take Me to Church," which eventually reached No. 2 for three weeks, beginning on the Dec. 20, 2014-dated tally, Fall Out Boy's "Centuries" became the band's first Hot 100 top 10 in eight years. The song peaked at No. 10 for two weeks (Feb. 7 and 14, 2015) and, in doing so, joined "Church," which then ranked at No. 3.

In all, 2015 was a relatively decent year for a variety of rock acts in the Hot 100's top 10, at least compared to the time since: In addition to Hozier (who technically first reached the top 10 in late 2014) and Fall Out Boy, Walk the Moon's "Shut Up and Dance" (No. 4, May 30) and Elle King's "Ex's & Oh's" (No. 10, Nov. 28) also reached the region. Comparatively, as twenty one pilots scored a trio of top 10s in 2016 ("Stressed Out," No. 2, Feb. 27; "Ride," No. 5, Sept. 10; and "Heathens," No. 2, Sept. 24), the only other rock songs to break into the top 10 last year were two legacy tracks by one act: Prince, whose '80s classics "Purple Rain" and "When Doves Cry" returned to the top 10 following his April 21, 2016, passing.

Meanwhile, "Believer" and "Feel" are the only two rock songs to permeate the top 10 in 2017 (among 55 total top 10s so far this year), and the first didn't break the barrier until early summer, when "Believer" bounded to No. 6 on the chart dated July 15.

But don't count out rock yet for the remainder of 2017: Along with any major releases or songs that, like Portugal. The Man's sleeper hit, might surge before the end of the year, Imagine Dragons' second single off Evolve, "Thunder," ascends to the top 30 on the latest Hot 100, leaping 40-30.
