As you said, they (EQ) definitely made a summer song, getting away from their usual type of songs. But I do like the way their voices work together on their "darkest" songs. I especially like this one...
I also must say that the Bonus song is incredibly good and is very close to what I usually hear...
QAR is a great song. You might also enjoy this one by "Black Dial". Apparently Black Dial broke up and some members went out n to form EQ.
C.C.Tay has some great songs. Mumkin Emes, On Solga are more dancey numbers. Her bubbly personality comes thru in her music.
I like this one, it's a little different, but it still catches my heart!
C.C.Tay is definitely an artist for me to keep a close look on.
