Lightbody started writing songs at the age of 15, in a little room under the kitchen of the family's house. He had few guitar lessons where he learnt the basics of the instrument but did not continue them, as he felt that one should not know any instrument "inside-out". He preferred to invent rather than use a formula. Today, he is not too fond of his earliest songs and thinks they "sucked". His songwriting style is mostly simple and basic, and he acknowledges that, saying he " advanced past rudimentary". He feels the best way to write an honest song is to be simple, and that trying to complicate matters distorts the intended message. He believes the band has always tried to keep things as "simple and pure" as possible and has written from the heart. One of Lightbody's major inspirations to begin writing was notable Irish poet Seamus Heaney; which is alluded to on the B-side track on Snow Patrol's "The Planets Bend Between Us" single, named 'Reading Heaney To Me'. It also refers extensively to Heaney's poems throughout the lyrics.
