Just Communication was not bad, Just Communication II was a bit better, personal opinion though. Some of the Two-Mix songs were pretty good. They released Rhythm Emotion, White Reflection, and Truth A Great Detective of Love from Detective Conan. Those are all pretty good, again, personal opinion.
There were also some other good songs, but do not remember them all. The ones mentioned were the ones often listened to. Last Impression is on the top though.
