SEKAI NO OWARI「Habit」

SEKAI NO OWARI’s hit song “Habit.” Many listeners were likely astonished by this track, which departs from their usual fantastical worldview and instead delivers somewhat caustic, realistic lyrics.

As the groove is emphasized throughout, the song sits within a generally standard vocal range for a SEKAI NO OWARI track, from mid1 C to mid2 F.

However, since the highest note (mid2 F) appears fairly frequently, it may be better to lower the key slightly depending on the singer’s range.

While it’s overall on the easier side, there are several rap-like sections, so it’s recommended to firmly memorize the flow that matches the lyrics.
