i suppose anything written with a dj in mind has held it back slightly, not the format as such.
but at the end of the day its dance music, best suited to being played in a club or at a party, by a dj who mixes the tracks with whatever tools he chooses.
i for one just like listening to songs, i like my music to have a begining, a middle bit and an end.
i think you can still be creative and yet dj friendly.
but i think most producers here will have written music that isnt so dj friendly, just as a way of letting loose and going wild with things
