The flashbacks to the 4th of July party are noted to be from 6 years ago, which would suggest it was 2008 since the current timeline would be December 2014. However, the song playing in the background ("Say Hey (I Love You)" by Michael Franti & Spearhead) was released in September 2008, thus making it impossible to be playing at the party that was 2 months prior to the release date.
