"Your Song" is actually a cover of the original song by Elton John. However, I can still explain the meaning and story behind Ellie Goulding's version. In the song, the narrator expresses their deep feelings for someone special in their life. They describe this person as having the ability to bring them immense joy and happiness. The narrator acknowledges that they may not have much material wealth, but if they did, they would provide a comfortable and beautiful home for both of them. The lyrics also convey the narrator's apologies for forgetting certain details about their loved one. It doesn't matter to them whether their eyes are green or blue, as they find them to be the sweetest eyes they have ever seen. The narrator dedicates this song to their loved one, stating that they can tell everybody that this is their song. They admit that the song may be simple, but it holds great significance now that it is done. The narrator hopes that their loved one doesn't mind them expressing their feelings in words and deeply believes that life has become wonderful since the person entered their world. Overall, "Your Song" by Ellie Goulding explores the deep emotions and gratitude the narrator feels towards someone who has made a positive impact on their life.
