Another question about the soundtrack

When they're eating Sushi, the song that's being played sounds very similar to It's Not My Fault (It's My Fault) by Discovery (the side project of Vampire Weekend's Rostam Batmanglij), but the vocals don't sound like Rostam's. Does anyone know if it is indeed that song or not, or is it a cover, or maybe the original song from which Discovery's version is a cover of.

BTW, I really like this movie!
