i havent dj'd for like 1 1/2 years now,due to my illness,but when i was playing at Party's/free partys/clubs/gathering ect ect almost every week,most of my sound was difefrent to other peoples.
Even if people know the tunes of others,i know that if i found out tunes others played,i still wouldent play them ,its just nice to have those tunes for personal use and whatever,people who try and sound like other dj's are not dj's imo.
