Hey Doll Baby

This is a sequel to 2001's "Reckless Abandon", and features the band looking back on their clumsy youth fondly.

I don't think it's necessarily about sex. It's about wanting to start the day with some love and affection. Maybe a warm cuddle. I'm not alone in interpreting it that way! For example: "'Just a Little Lovin’ is a timeless country song originally recorded by Eddy Arnold in 1954. The song, written by Eddie Miller and Jimmy Campbell, explores the delicate nuances of love and showcases Arnold’s emotive vocals. It delves into the universal theme of love and how even the smallest gesture of affection can have a profound impact on our lives." https://oldtimemusic.com/the-meaning-behind-the-song-just-a-little-lovin-by-eddy-arnold/

There aren’t many things that’ll hurt more than giving love a chance against your better judgement only to have your heart crushed yet again. Ed Sheeran tells such a story on “Page.” On this track, he is devastated to have lost his lover and even more saddened by the feeling that he may never move on from this.

“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.

In the 1980s, sunglasses were a common fashion for people who wanted to adopt a "tough guy" persona (note all the cop shows from that era -- Simon & Simon, Miami Vice, etc. -- where the lead characters wore shades). So I think this song is about a guy who wears shades as a way of hiding his insecurity after learning that his girlfriend is cheating on him. He's trying to pretend that he's a "tough guy" to hide the fact that his girlfriend's affair is disturbing him.
