First I have to admit that I LOVE Tokyo Project, The Collection. Some of the tracks aren't new on The Collection, but is the very best mix of the very best tracks I know (Doctor Pressure, Nasty Girl, Can't Fake It, etc.). Perfection.
For me Tokyo Disco didn't have the same instant gratification, or the perfect mix of (often familiar) stuff. I found I could get into the 'harder'/louder third cd very quickly, but cds one and two took a few listens. It is worth it though. There are some really special but more subtle tracks here (Rise, Borderline, Something to make you feel alright) as well as the awesome loud stuff (SOS, The Master, Hold Your Head Up Hight, etc.).
Mark Doyle definately has it, although I fear a lot of the criticism placed on Hed Kendi since he left has been very bitter and biased. Nu Cool, for example, has some amazing gems tucked away if you give it some time.
