"I Know There's Something Going On" by Frida, aka Ani-Frid Lyngstad of ABBA, is an intense slab of righteous relationship paranoia. The drums and the background vocals, both provided by Phil Collins (operating firmly in "In The Air Tonight"/"Take Me Home" mode) keep this song's tightrope near the snapping point from start to finish. This was the most successful non-ABBA song from any of the four Swedes. One listen and it's clear why.
