Thanks for these comments, dj_ch3mical and segwist.
I think Happy Hardcore isn't finished, in France we've got lot of "rave party". In these parties lot of creation are going on, Trance, "tekno" (Daft punk -like), drum and bass, hardtek, hardcore...
And of courses there are not only DJs, there are "livers" who plays their own music with machines and/or computers (like me).
So I think my song could be welcome in parties, live played with my computer, with a good audio system, with big bass... mmh
My bass synth sound was chosen for that.
And of course I had fun playing this song with no samples taken from the original song (all played with my midi keyboard with some vsti).
I like your remix too, and I don't think your bassline is boring, the brothers has songs with long lines not changing too, but it's a rythmic, the centre of the song I think. And with a good audio volume, and good quality you could hear all the tiny good sounds that makes your song not boring.
