he references May 5th a few times which was the release date for All the Beauty in This Whole Life, so some, most or all of these are from that time period.

As a side-note, I kinda dig these little EPs of short songs as vehicles for artists to get some new ideas out there and keep their music on people's radars/wet their fans' beaks until their next official project drops. Kota's dropped one of these each of the last few years and I wouldn't mind it becoming a trend.
