To each their own I say. I used to love Tiesto hardcore, but every since he DJ'ed for the world at the Greece Olympics, he started going down hill and I slowly switched to Armin and now love him as much as I did Tiesto back in the day.... Buuren FTW!
Reason why I love Armin so much is beacuse he puts himself into his music... He makes the best tracks that he possibly can and I think he is a lot more in tune with the trance scene then Tiesto (now a days anyways). The other reason is because the man is brilliant... He decided to finish off a law degree as a Plan B just in case his DJ'ing career did not go very well. I have a ton of respect for him because of this.
Tiesto's days are almost over and I think it is time for newer and younger talent to rise to the top! OUT WITH THE OLD IN WITH THE NEW I SAY!!!
