I had to dig to the depths of my brain for this one. A song that reminds you of your most recent ex (coming up on four years ago, I can barely remember what I had for dinner two days ago). The most recent ex loved Slipknot. They’re okay in my book, but I’ve never rushed out to buy their album. This song he played when he was happy, sad, angry, drunk, sober, drunk (yes I said that twice), depressed. Slipknot all the time.
