If you had a difficult baby then there will be a song or an album that can take you straight back to moments of desperation. Moments when you were trying to get that baby to sleep. Usually in the middle of the night.
There will be a CD that for a time you somehow became convinced worked on your baby, magically soothed it. It was their special CD. It probably won’t have even been a particularly special CD to you, it is just the most baby-friendly CD in your collection you could find while sorting one-handed. And you will have rocked and danced your baby to this CD over and over again, until one night you finally realised that there was no magic trick, nothing can put this goddamn baby to sleep. You are going to die of sleep deprivation instead. To the sounds of your stupid CD.
For about, oooh a year, you’ll be too tired to change that CD out of your stereo. So naturally it will be several years before you can possibly stand listening to it again. And when you do, you will be transported immediately back.
