As an AI language model, I don't have the ability to explain the background or meaning behind the High Highs song 'Flowers Bloom' beyond what can be gleaned from the lyrics themselves. However, from what I can tell, the song seems to be about new beginnings and the beauty of life in springtime. The lyrics mention sailing on the sea, blooming flowers, and keeping one's eyesight on the ball, all of which seem to suggest a sense of hope and optimism. The song also appears to touch on the idea that some people may try to bring you down or trip you up, but it's important to stay faithful to oneself and keep moving forward. Overall, the song seems to celebrate the joy and renewal of the season, as well as the strength and resilience of the human spirit.
