There are a few songs that managed to become burned into our memories even if you don't actually remember listening to the song.

It doesn't really matter how many years have passed, as soon as MMMBop comes onto a speaker you are going to start singing along. The problem is, Hanson says we have been singing it wrong for all these years?! GiphyThe Hanson brothers are all grown up
