Was totally stumped by Omi- even after seeing the symmetry... I started googling MIS, OMIS, ROMIS... I didn't drop the S. Whoops! Fortunately, I noticed the other letters and was able to get NAME for the artists that took up a whole answer, and DRP for the ones that didn't... wasn't too hard to get to the O for NAME DROP at that point! Good puzzle. Glad I stuck with it and figured it out!
