The song "Somebody That I Used to Know (Adrock remix)" by Gotye ft. Kimbra explores the aftermath of a failed romantic relationship. The lyrics discuss the feelings of nostalgia, sadness, and resentment that arise when thinking about an ex-lover.

In the verses, Gotye reflects upon the past and the moments they shared together. He acknowledges the happiness he once felt but also the loneliness he experienced in the company of his partner. Despite the pain, he admits that love is still a lingering ache in his memory.

The chorus reveals his frustration and hurt over the way his ex-partner treated him after the breakup. He feels cut off and discarded, as if their relationship never mattered. Despite claiming that he doesn't need their love anymore, he still feels the sting of being treated like a stranger, which leaves him feeling rough.

Kimbra's verse further delves into the experience of being wronged in the relationship. She reflects on the times when her partner betrayed her, making her believe she was always at fault. She expresses a desire to move on from that toxic dynamic, not wanting to interpret every word her ex says as a hidden insult. She mentions that her ex-partner claimed they could let go, implying that they wouldn't be hung up on the past, but the reality seems different.

The song ultimately portrays a sense of hurt, disillusionment, and the difficulties of moving on from a past relationship. It explores themes of emotional manipulation, feeling replaced, and the struggle to let go of someone who was once significant in your life.
