Jung Kook, one of the seven members of the massively popular K-pop band BTS, has finally unveiled his debut solo single, "Seven." Since its release this morning, fans have rushed to support the song by purchasing it in large numbers, and their love is evident by looking at the iTunes chart in the U.S.

At the time of writing, Jung Kook occupies an impressive five spots inside the top 40 on the iTunes chart of the bestselling tunes in the U.S. His new single, "Seven," reigns in many forms, but it isn't the only track from the superstar that is performing well in this exciting moment for the singer.

Jung Kook's "Seven" sits at both No. 1 and 2 on the iTunes America chart, as fans are purchasing both the explicit and clean versions of the tune in large numbers, outpacing any and all other new releases. Even tracks from well-known artists like City Girls, Post Malone, and Billie Eilish haven't been able to keep up with demand for “Seven.” The instrumental version of the same title is also performing strongly, securing a spot within the top five as well.

If having three editions of the same song selling well enough to rank among the top five biggest hits on iTunes wasn't enough to proclaim Jung Kook a bestselling star, his two other recent releases are also experiencing a resurgence. In the wake of the incredible success of "Seven," Jung Kook's "Still With You" and "My You" have returned to the top 40 region on the iTunes ranking, once again becoming hits in their own right.

In anticipation of the release of "Seven," Jung Kook gave both "Still With You" and "My You" a wide release several days ago. These tunes are actually several years old but were not previously available to stream on most platforms, and Americans couldn't purchase them on storefronts like iTunes. Following their wide release, the songs debuted on a handful of Billboard charts this week and are now selling well again. This resurgence can be attributed to the immense popularity and excitement generated by "Seven."
