R3HAB and Korolova's Hi Hello Climbs to No. 2

Plenty of festival IDs go viral and then fade. R3HAB and Korolova turned theirs into a chart run.

R3HAB & Korolova – Hi Hello [Tomorrowland Music] is No. 2 on 1001Tracklists' trending chart in this morning's 7:04 AM PT snapshot. Only MORTEN's Gimme Dat is above it. It was No. 2 yesterday too, its best spot since it first showed up in our daily snapshots on Saturday, Oct. 17. The official release came out on Friday, Oct. 23.

The MainStage moment

According to the label, the record had already been tested in DJ sets for a few months. The big moment came at Tomorrowland 2026: during R3HAB's MainStage B2B with Afrojack, he brought Korolova out so the two could play it together for the first time. The footage went viral on 1001Tracklists and other channels.

The track is short and built for big rooms. It opens on a delicate vocal, moves into a synth-driven build and then hits a festival-sized drop, all in 2 minutes 37 seconds.

"It's one of those tracks that gets an immediate reaction from the crowd," Korolova said in the release announcement. R3HAB said the two had been "perfecting this record all year," and called the Tomorrowland premiere electric.

The run so far

Hi Hello has been in the top 10 of the trending chart in every one of our daily snapshots since it arrived:

• Oct. 17: No. 9 (first appearance)
• Oct. 18: No. 5
• Oct. 19: No. 6
• Oct. 20–21: No. 3
• Oct. 22: No. 4
• Oct. 23 (release day): No. 6
• Oct. 24–25: No. 2

Dramma set the stage

This is R3HAB's second strong run on the trending chart this month. R3HAB & ARTBAT – Dramma [UPPERGROUND], with ARTBAT, came out on Oct. 2. It was No. 1 on trending in each of our first nine daily snapshots, from Oct. 9 through Oct. 17.

Then the two records crossed paths. On Oct. 18, Dramma slipped to No. 11 while Hi Hello jumped to No. 5. Dramma left the trending top 20 this morning, but DJs are still playing it: it's No. 4 on this week's 1001Tracklists weekly DJ chart, supported by 76 DJs.

Two artists on different paths

The pairing makes sense on paper. Korolova came in at No. 36 in DJ Mag's Top 100 DJs 2026, up 14 places. DJ Mag notes that the Ukrainian DJ and producer launched her own label and party series, Captive Soul, in 2025, and has released music on Drumcode over the past year. You can hear both sides in our library: Goodboys & Korolova – The Present on Captive Soul and Volkoder & Korolova – Waiting for You on Drumcode.

R3HAB placed No. 45 in the same poll. DJ Mag's write-up puts his album Dream inside a dream… at the center of his year. It's his first full-length in eight years, recorded partly in Marrakesh with field recordings of traditional snake-charmer flutes, and it's the first time he sings vocals himself. It came out on July 31.

Catch R3HAB in SoCal

R3HAB is on the lineup for Countdown NYE, Insomniac's two-day New Year's festival at NOS Events Center in San Bernardino on Thursday, Dec. 31, and Friday, Jan. 1. Check the official site for his day and set time.

Why it matters

A viral festival clip usually means a spike, and then people move on. Hi Hello did the opposite: it spent six days on the trending chart before it was even out, then climbed again after release. R3HAB has now had two different records in the trending top 10 in October: a melodic collaboration with ARTBAT and a festival one with Korolova. That shows how many kinds of DJs are playing his music right now.
