Yacht Club. is one of the co-winners of Galantis' single "Runaway (U & I)" remix contest from October 2014. I've been listening to this trap rework of the song on repeat lately. While it's a slowed-down version of the original, the anticipation that builds to Yacht Club.'s shrill, energetic future bass chorus makes the song suitable for both chill-out sessions and for getting pumped up.
I found this song from my friend Kirk's hour-long September Mix — he showcases my favorite bit of the song (that killer second, arpeggio-like drop).
