It's their own format called "The Current", unaffiliated with the MPR "Current". I would call it a pop hits format, sort of along the lines of KNHC but with less of a dance vibe. Was passing through on 18 yesterday (a rarity for me) and listened for a short while. Heard a legal ID at 1602, was for "KGRG-FM HD-1 Auburn and K207AP Sumner-Lake Tapps". They are not currently running an HD signal and K207AP was cancelled back in January. This ID is sort of legal I suppose if I'm remembering correctly but more importantly it shows that they are putting the minimum effort into keeping the license alive, what with not making the legal ID's 100% legal and just firing up the automation computer again. At least the ID is near the top of the hour.
Expect it to go silent again in a couple of weeks at most.
