The sound is kind of like "Return to Innocence" and it was a 90s song...the person in the background is vocalizing the same words over and over and then at the end, the main singer starts singing "doo doo doo doo doo". This is NOT "Tom's Diner" by Suzanne Vega.

Here is audio of the tune of the person in the background:
