Song Titles Not in the Song by LivenickT

Question 1

We'll start off on the easier side. What song by a rather unimaginatively named band from the early '90s has a name that was chosen as a near synonymous phrase from the repeated line in the chorus? The line from the chorus was not chosen as the song title because it was the same as a famous Marvin Gaye song.
