Bagatelle

Ed Sheeran sings about missing his former partner and learning important life lessons in the process on “Punchline.” This track tells a story of battling to get rid of emotions for a former lover, whom he now realized might not have loved him the same way. He’s now caught between accepting that fact and learning life lessons from it and going back to beg her for another chance.

“Head > Heels” is a track that aims to capture what it feels like to experience romance that exceeds expectations. Ed Sheeran dedicates his album outro to a lover who has blessed him with a unique experience that he seeks to describe through the song’s nuanced lyrics.

“Plastic Bag” is a song about searching for an escape from personal problems and hoping to find it in the lively atmosphere of a Saturday night party. Ed Sheeran tells the story of his friend and the myriad of troubles he is going through. Unable to find any solutions, this friend seeks a last resort in a party and the vanity that comes with it. “I overthink and have trouble sleepin’ / All purpose gone and don’t have a reason / And there’s no doctor to stop this bleedin’ / So I left home and jumped in the deep end,” Ed Sheeran sings in verse one. He continues by adding that this person is feeling the weight of having disappointed his father and doesn’t have any friends to rely on in this difficult moment. In the second verse, Ed sings about the role of grief in his friend’s plight and his dwindling faith in prayer. “Saturday night is givin’ me a reason to rely on the strobe lights / The lifeline of a promise in a shot glass, and I’ll take that / If you’re givin’ out love from a plastic bag,” Ed sings on the chorus, as his friend turns to new vices in hopes of feeling better.

I think the meaning is pretty clear. This person got really burned in a previous relationship, and because of this is unable to love and show care in his present one, even though he so badly wants to. It's lovely song, and very sad. You can really feel how defeated and frustrated he is with himself.

Per the FAQ on Keane's website, Keane's drummer Richard Hughes, stated the following: "We've been asked whether "Somewhere Only We Know" is about a specific place, and Tim has been saying that, for him, or us as individuals, it might be about a geographical space, or a feeling; it can mean something individual to each person, and they can interpret it to a memory of theirs... It's perhaps more of a theme rather than a specific message... Feelings that may be universal, without necessarily being totally specific to us, or a place, or a time..." With the nostalgic sentiment and the overall tone of the song, I think Keane is attempting to express a Portuguese term known as 'saudade', which does not have a direct English translation but roughly means "that which we remember because it is gone."
