I dont personally mind scratching, ill be the first to admit im shit at it myself but I add a little when practising, loop a beat and just mess with it, but its the same with fx too much of it can ruin a nice song selection.
Fair play to the dj’s that can scratch well but a lot of night clubs that are mainstream its more about pop/dance/top 40 mixed in a mediocre manor. I think its the underground dj’s that put more effort into there techniques and think outside the box, (not dissing the pop/chart dj’s as some can be amazing and go out of their way to spice up stuff but I find a lot do it for image where I live, follow the crowd and not the music they personally like)
