This week, Anime News Network reported that the new opening theme song for "Attack on Titan" Season 4, Part 2 hit a surprising new milestone. Per the anime-focused outlet, the final season's Part 2 opening theme, titled "The Rumbling" by SiM, made its way onto the Billboard Hard Rock chart shortly after its debut on January 22. The song debuted at #3, and on Saturday, it was elevated to #1 (via Billboard), after racking up a whopping 10 million playbacks. The opening animated sequence has been viewed on YouTube 30 million times, further cementing its popularity.

The Billboard 100 is the safe haven for music's best of the best. Reaching the #1 spot on the Billboard Top 100 is the musical equivalent to dominating the box office or landing on the Netflix Top 10. It brings with it a level of notoriety for outpacing all the available content competing against you. The song in a movie brings with it an even bigger luster considering it is a song distracted by visuals during its release. When it is on a TV show, it is unheard of, which makes the feat a big win for "Attack on Titan."
