Thanks to this publicity coupled with a social media push by the bassist of Punchline (who stated that he would put down the bass if the EP did not reach No. 1 on iTunes), the record achieved the rank of No. 1 on the iTunes Rock charts and No. 7 on the main charts at its peak, as well as No. 4 on Billboard's Heatseekers charts.
