Personally I like the sound of it with everyone in it but it just sounds like all of TK's recent stuff. Can he not arrange things using different instruments?! It sounds like Aitai Riyuu and Makenai Kokoro X_X + TK composed and arranged ayumi hamasaki's new single 'crossroad' which features a cover of an old TM Network song called 'SEVEN DAYS WAR'. I wish avex would get over the whole renewed interest in TK cuz frankly he's rubbish
