Подснежниками refers to "snowdrops", which are delicate white flowers that are among the first to bloom in early spring, often pushing through snow.
In the song, the line "Пока тело не укрыло подснежниками" (Until the body is covered by snowdrops) is a poetic and somewhat melancholic way of saying "before death" or "before I'm buried". It's a beautiful and evocative image that contrasts the fragility of life with the enduring cycle of nature, making it a memorable and unique word choice for the lyrics.
Xolidayboy's "ПОМНИ (POMNI)" is a really intense song about a deep, almost spiritual connection between two people. The singer feels lost and silent, saying "А на экране кто-то шепчет Чтоб не слышать Как я молчу" [And someone whispers on the screen So I don't hear How I'm silent]. He remembers a first dance and wanting to be with this person, even on a roof with flowers.
The core of the song is a plea to remember how this person saved him. He sings, "Помни, ты напомни Как из пустоты меня ты позвала" [Remember, remind me How you called me from emptiness] and "Как убитый мир мой вновь ты собрала" [How you reassembled my broken world]. This person is his salvation, like angels saving sinners, and he's the temptation. Even when told to leave a "dull establishment" because the doors are closed, they can't break away from each other. It's a powerful story of being brought back to life by someone who means more than words.
