K-pop Monthly! May // My Favourites (2)

I know this is 50 years late. I tend to make them at the beginning of the next month, but june was exam month for me and I had absolutely no time.
As always:
1) Only one song per artist cause otherwise my faves would take too much space.
2) Only releases from the month count. If it's an MV for a song released in a different month it doesn't count.
3) With repackage albums only new songs count.
