Hearts2Hearts Achieves First Terrestrial #1 with ‘RUDE!’: A Record Beyond Numbers
On March 14, 2026, the protagonist of MBC’s ‘Show! Music Core’ was Hearts2Hearts. While achieving their first terrestrial #1 on the final broadcast (makbang) of this promotion resonated emotionally with both the artist and the fandom, from a data analyst’s perspective, this win was a victory of thoroughly calculated figures. The chart trends and score composition shown by ‘RUDE!’ demonstrate the classic route for an idol from a mid-sized agency to break through the firepower of major agencies and reach the top in the recent K-Pop market.
Looking at this week’s Music Core score results, Hearts2Hearts held an overwhelming advantage in digital music scores and real-time voting. They recorded a total of 7,450 points, beating the second-place candidate by about 800 points, which exceeds the average winning score of 7,100 points on Music Core over the past four weeks. In particular, the unique nature of it being the final broadcast maximized fandom solidarity, leading to a perfect score in real-time voting (1,000 points), which became the decisive factor for the win.
The Solidity of Digital Music Scores: The Secret to ‘RUDE!’s Long Run
Evidence that Hearts2Hearts’ #1 win is not just a result of ‘fandom firepower’ lies in the digital music scores. Despite entering its third week of release, ‘RUDE!’ is firmly maintaining its position within the top 10 of the Melon TOP 100 chart. Analyzing the data, the streaming drop rate compared to the first week of release is only 4.2%. This contrasts with general idol songs, which typically show a drop rate of 15-20% in their second week.
Achievements on the YouTube Music Korea chart are also notable. Recording 5.2 million weekly streams proves that they have secured public recognition. In particular, users in their teens and 20s account for 68% of the total, completing a virtuous cycle where the challenge craze on TikTok and Shorts leads to actual music consumption. The data suggests that ‘RUDE!’ has secured general ‘listeners’ beyond just a fandom song.
“Honestly, this song is so good that I keep hearing it on the streets. There’s a reason it’s stuck on the charts. I’m glad they won #1 on their last broadcast.”

Correlation Between Album Sales and Fandom Solidarity
Combining data from Circle Chart and Hanteo Chart, Hearts2Hearts’ first-week sales for this album recorded 320,000 copies, a 145% growth compared to their previous work. This is a career high for the group. Notably, daily sales did not drop below 10,000 copies even in the second and third weeks of release. This is a significant indicator that the influx of new fans continued throughout the promotion period.
The album score allocation for Music Core is based on a maximum of 1,000 points, and Hearts2Hearts earned 890 points here. Compared to competitors with relatively higher digital scores, they were able to secure an advantage in album scores and take a favorable position in the total score competition. It shows that the fandom’s purchasing power led to strategic consumption for music show ranking competition beyond just ‘collecting.’
SNS Index and the Impact of Short-form Content
The most striking data in this ‘RUDE!’ promotion is the SNS index. Official music video views have surpassed 24 million, and views for the related hashtag (#RUDE_Challenge) have exceeded 100 million on TikTok alone. According to Music Core’s SNS score calculation method, YouTube views and social media mentions carry significant weight, and Hearts2Hearts received near-perfect scores in this category.
Data analysis shows that the spread of challenge videos peaked on the 10th day of release. This is somewhat later than the viral curve of typical idols, but this timing coincided with the music show ranking aggregation period, maximizing the score effect. It shows typical data of a song that gains momentum and stays on track.
“Did you see them doing the encore live? Even while crying, their pitch didn’t waver at all, they nailed it. No one can say anything because they won #1 with talent.”

The Industrial Weight of a Terrestrial #1
There is a significant industrial difference between winning #1 on cable music shows (The Show, Show Champion) and terrestrial ones (Music Core, Music Bank, Inkigayo). This is because a terrestrial #1 is only possible when the trio of public popularity, album sales, and fandom voting power are perfectly aligned. Especially in 2026, with the reorganization of music charts making it harder to enter rankings through fandom ‘streaming’ alone, Hearts2Hearts’ achievement is even more valuable.
Due to this #1 win, Hearts2Hearts’ advertising rates and event booking fees are predicted to rise at least twofold compared to the previous quarter. According to data, an artist’s brand reputation index tends to rise by an average of over 40% after achieving their first terrestrial #1. Hearts2Hearts is also likely to enter the TOP 5 in the brand reputation index to be announced next week.
“People call it a miracle of a small agency, but this isn’t a miracle; it’s talent proven by data. The eye for picking the song and the marketing timing were artistic.”

Future Outlook: What is the Milestone for the Next Comeback?
Hearts2Hearts’ current promotion has reached a data-driven conclusion of a ‘successful wrap-up.’ Now, the indicator to watch is ‘sustainability’ in the next comeback. Looking at past data, whether first-week sales exceed 500,000 copies in the next album after the first terrestrial #1 becomes the watershed moment for entering the ‘top-tier’ group category.
Additionally, the predicted Melon annual chart ranking for ‘RUDE!’ is within the top 30 if current trends continue. This means the group’s public base has become solid, providing data to expand the scale of overseas tours. In the next album, whether they enter the Billboard 200 chart will be a key indicator for judging their global growth.
In conclusion, Hearts2Hearts’ #1 win was not mere luck. It is a collaborative product of short-form marketing through thorough targeting, strategic fandom voting, and above all, the digital power of the song ‘RUDE!’ itself. Data does not lie, and Hearts2Hearts proved their value at the peak of those numbers today.
