Plus, frontman Kevin Cronin tops Rock Songwriters.

Netflix's Ozark helps send four classic hits by REO Speedwagon onto Billboard's rock charts, dated April 11.

The crime drama's third season dropped on March 27, and the band is central to the third episode, "Kevin Cronin Was Here," named for the group's lead singer.

"We are big fans of Ozark here in the Cronin house, and have been waiting patiently for Season 3," Cronin wrote in a post on REO Speedwagon's official website. "The family will be snuggling up and going on a major Ozark binge this weekend. Be safe and take care."

Following the episode's premiere, the band charts four of its biggest hits on the Hot Rock Songs survey, which blends streaming, airplay and sales data. Here's a rundown, along with the tracks' on-demand U.S. streaming and sales totals and gains in the week ending April 2, according to Nielsen Music/MRC Data. "Time for Me to Fly" makes the greatest percentage surges, having received the most prominent spotlight of the four songs in the episode.

No. 10, "Keep On Loving You"

1 million on-demand streams, up 12 percent

1,000 sold, up 279 percent

(originally a one-week No. 1 on the Billboard Hot 100 in 1981)

No. 13, "Can't Fight This Feeling"

809,000 on-demand streams, up 9 percent

1,000 sold, up 268 percent

(No. 1 on Hot 100, three weeks, 1985)

No. 15, "Time for Me to Fly"

581,000 on-demand streams, up 98 percent

5,000 sold, up 1,961 percent

(No. 56 on Hot 100, 1978; re-entered in 1980)

No. 16, "Take It On the Run"

664,000 on-demand streams, up 14 percent

1,000 sold, up 347 percent

(No. 5 on Hot 100, 1981)

Meanwhile, Cronin debuts at No. 1 on Billboard's Rock Songwriters chart, thanks to his having solely written "Keep On Loving You," "Can't Fight This Feeling" and "Time for Me to Fly." The band's late lead guitarist Gary Richrath (who died in 2015) debuts on Rock Songwriters at No. 8, thanks to his having solely penned "Take It On the Run." Cronin and Richrath concurrently tie at No. 8 on Rock Producers, as they co-produced the four songs.

Notably, with Cronin conquering Rock Songwriters, he tops a Billboard chart for the first time since "Can't Fight This Feeling," which spent its third and last week atop the Hot 100 dated March 23, 1985.

Plus, the band's 1988 collection The Hits, which includes all four songs, enters Top Rock Albums at No. 49, up 85 percent to 4,000 equivalent album units.

The weekly Hot 100 Songwriters and Hot 100 Producers charts are based on total points accrued by a songwriter and producer, respectively, for each attributed song that appears on the Hot 100; plus, genre-based songwriter and producer charts follow the same methodology based on corresponding "Hot"-named genre charts. As with Billboard's yearly recaps, multiple writers or producers split points for each song equally (and the dividing of points will lead to occasional ties on rankings).

The full Hot 100 Songwriters and Hot 100 Producers charts, in addition to the full genre rankings, can be found on Billboard.com.

Ozark is produced by MRC, which shares a parent company (Valence Media) with Billboard.
