Someone Like You: The song was inspired by a broken relationship of Adele with her ex-boyfriend.Adele sad: "Well, I wrote that song because I was exhausted from being such a bitch,
With 'Rolling in the Deep' or 'Rumour Has It'...
I was really emotionally drained from the way I was portraying him,
Because even though I'm very bitter and regret some parts of it,
He's still the most important person that's ever been in my life, and 'Someone Like You.
I had to write it to feel OK with myself and OK with the two years I
spent with him. And when I did it, I felt so freed.

Turning tables: 'Turning Tables' was conceived following a confrontation with Adele's ex. In the studio, Adele had gotten upset and emotional that her ex had kept
"turning the tables" on her during their fights,
And Ryan Tedder used this idea as a concept for composing the song.
