The lyrics to Snow Patrol's song "Run" describe a bittersweet moment between two individuals who must part ways, perhaps forever. The first stanza sets the stage for this departure, with the singer acknowledging that the person they are leaving behind has been the only good thing in their life. However, despite this acknowledgement, the singer finds it difficult to look at the individual directly. This may suggest that the separation is painful and they cannot bear to see the hurt in their companion's eyes. However, the singer maintains that even though they may be apart, they will "make it anywhere, away from here."

The second stanza contains the most famous lines of the song, with the repeated command to "light up, light up." This phrase can be interpreted in multiple ways, from an encouragement to keep going, to a plea for the individual to show some sort of response. The singer continues to assure their companion that they will always be by their side, even if they cannot hear their voice. The chorus then culminates with the declaration that they will "run for our lives," suggesting that this departure is an escape from something, perhaps the negativity or pain they have experienced.

The final stanza slows down the pace of the song, with the singer asking for a reprieve from the chaos that has enveloped their minds. Nevertheless, they reassure their companion that "we're bound to be afraid," and that short-term fear is worth it to escape the mess they find themselves in. The song concludes with another reiteration of the chorus, with the singer pledging once again to be there for their companion, no matter what.

Overall, "Run" is a powerful song that captures both the pain and the hope that comes with major life changes. The repetition of the chorus adds to the intensity of the emotion behind the lyrics, making it a memorable and moving piece of music.
