There seemed to be a phenomenon in the 90s where a band would have 2 pretty big hits within a short time frame. I wouldn't call them two-hit wonders because most of them had success for quite a while, but, inevitably, their back-to-back hits were the biggest.
Let's start it off with one of the biggest pop bands of the 90s, one that I've overlooked so far: Barenaked Ladies! As always, click the pictures for the videos.
"One Week" (1998)

"It's All Been Done" (1998)
