Along with its artwork, the hip hop track titled "Sleep Tight" distinctively reveals E-Sens' lyrical artistry and mysticism. His voice is composed and serene, marking moments of his daily life in parts like the hook of the song. FRNK, the producer behind "Sleep Tight," complements the lyrics with an entrancing and dreamy beat. 

Aside from enjoying this new track, fans are also paying particular attention to FRNK. Back on February 14, BANA displayed the name 'XXX' and a remix track by producer FRNK with no particular information, sparking rumors and leaving fans with questions unanswered. Some are speculating with this new release that FRNK may be BANA's next, upcoming artist. 

In other news, E-Sens is preparing to release his highly-anticipated, first official album '[The Anecdote].' According to a source closely related to BANA, "Sleep Tight" will not be included in '[The Anecdote].' However, this unexpected release has certainly set '[The Anecdote]' to a much higher expectation, causing excitement among fans.
