ARMY fandom was hyped up after they listened to the new Coca-Cola Indonesia commercial as they recognized BTS voices singing a rock genre in the ad, especially Jungkook's. Not a surprise since anyone can easily distinguish Jungkook's voice due to its unique flair, even with a little raspiness of his rock voice.

Fans went into a collective frenzy after it was revealed that BTS indeed sang for the ad, and they were singing praises and raving about Jungkook's rock voice and his crystal clear English pronunciations. Jungkook's voice turned growly, raspy, and bold for a rock song, and the main vocalist nailed it. As stated by the media, "Jungkook electrify in Coke Ad."

In addition, fans were marveling at the versatility of Jungkook's voice, how he can pull off any genre flawlessly. Some of the fans' comments:

Following this, many "Rockstar Jungkook" edits popped up, and the old ones (especially those Jungkook x Arctic Monkey edits) resurfaced. Fans love how Jungkook's overall styling actually fits the rockstar image perfectly, especially with his long hair, powerful stage presence, and overflowing charisma.

Many even wish for a rock genre song to be included in Jungkook's future mixtape/solo album.

As a result of all the hype, 'ROCKSTAR JUNGKOOK' trended worldwide on Twitter.
