Перекотиполем literally translates to "tumbleweed". It's a vivid and somewhat rare word in song lyrics, evoking a strong visual.
In this song, the artist uses it metaphorically in the phrase "не будь перекотиполем" (don't be a tumbleweed). He's advising his daughter not to be rootless, aimless, or easily swayed, but instead to be grounded and connected to her country. This makes it a powerful and culturally resonant word.
"Mi" is YARMAK's letter to his young daughter, written as a lullaby.
He looks back at his own childhood and forward to hers, promising to lay the foundation for her life and to lead by example rather than just words. He admits he won't always be nearby, sometimes protecting her means being away, but tells her she is worth more than his own life.
The middle of the song turns into advice: love your country, learn from your own mistakes, hold on to a sincere heart, and never let your word be worth less than your promise.
It closes as a bedtime scene. He sings her to sleep, promises to stay close through every season, and calls her his talisman, the thing that keeps him going just as much as he protects her.
