The Script frontman Danny O'Donoghue explained the song's meaning in a track-by-track interview with The Independent
"The song Mad Love – it couldn't be a Script album if we didn't talk about relationships and the kinda crazy relationships that people have. I tend to go for those ones that have a bit of love and hate in there, there is angst, there is push and pull but even - although you may be in a tumultuous relationship - you do it for the love and sometimes you might fight just to make up.
Sometimes you break up just to get back together again. That's what this song is about, it's when you have a mad mad mad love. It's something that you can't walk away from, something that you know is going to be around for a long long long time. It's a fun song and it's got a really cool beat."
