The song "Horses" by High Highs speaks about childhood memories and the innocence that comes with it. The lyrics talk about riding horses and singing, something that brings the speaker joy and comfort. Later in the song, the speaker asks to be spoken to in a softer tone, indicating a desire for gentle communication and connection. Overall, the song seems to be a nostalgic reflection on childhood and the things that bring us happiness and peace. The repeated phrase "by and by white horses go" could be interpreted as a reminder that time moves forward and things change, but the memories and emotions associated with those experiences remain.
