Углекислый (uglekislyy) is a scientific adjective meaning "carbonic" or related to carbon dioxide. It's an incredibly rare and creative word to find in a pop song, which makes it a real standout.
ANNA ASTI uses it metaphorically, singing about her lover being a "gulp of oxygen in a carbonic world" ("глоток кислорода, в мире, где углекислый"). She paints a vivid picture of a suffocating, toxic environment, highlighting just how vital and life-giving this new love feels in comparison.
Верю В Тебя is a vibrant pop confession where ANNA ASTI celebrates the moment someone finally breaks through her walls of doubt and turns past disappointments into distant “white noise.” Waking up before dawn, she slips away from an old life of half-hearted romances and dives into a love so real that even comfortable silence feels electric. The lyrics paint the couple as invincible teammates who vow to protect the spark that healed her scars and filled his emptiness, tossing every “almost-feeling” that came before into oblivion. Yet beneath the euphoria lies a fragile plea: if this trust is ever betrayed, she fears she will never believe in love again. The song is a joyful, high-energy anthem to second chances, mutual rescue and the exhilarating faith that comes from finally finding your true oxygen in a carbon-laden world.
