As for DJs ruining the Trance scene, i agree, AvB, A&B and their troop only play boring progressive with fart sounds and random 'melodies'.
But, not only progressive is ruined, for me Daniel Kandi already ruined the Uplifting Trance scene with his tracks that sounds the same thing over & over & over.... It's 'easy' to listen to this kind of trance. So, guess what what happened? Producers are now making tunes like Daniel Kandi does and uplifting trance is now boring as hell.
That's my opinion.
