I'm back with another mashup! This time, it's for 9MUSES' GYEONG REE's debut song, "BLUE MOON", together with SF9's "O Sole Mio". I apologize if some parts sound a little messy. "O Sole Mio" doesn't have an official instrumental so I had to use what I can use. I hope you still enjoyed this one!

I do not own anything. All media involved (excluding the mashup) belong to their respective owners.
