Released in 2013, "Kiss This" stands as a defining track from Demi Lovato's evolution from teen pop to a mature pop-rock artist. The song features a driving, guitar-heavy arrangement that anchors its themes of heartbreak and self-empowerment. It marked a significant shift in her sound, moving away from her earlier, more polished production toward a grittier, more authentic style that resonated with her growing fanbase. The track was a commercial success, reaching the top of the US Billboard Hot 100 chart and solidifying her status as a leading voice in contemporary pop music during that era. Its enduring popularity highlights Lovato's ability to craft songs that address universal emotions of loss and resilience with genuine vulnerability and musical strength.
