Reply to If I Play Music....

Ok so I play to mostly military and UK scene, I'm american I have a vast rage of music and just conjured this thought up.
If I Play Music that I believe people are listening to such as top 40 and such... and dont add any of my own flavor or finding something that will set me apart and make my sets different to gain popularity, how is this making me a better dj in the long run?..Ive been djing for a while and anyone I play for tell me i rock lol...not mening to brag i have been playing for like 5 years with vdj and traktor pro and FL studio more on the producing side. Being im only 23 on the 15th .. I still have years of knowledge I need yet I know. But yet where should I go from here?...What are the most versatile setups that the big names are using?...are they using samples and piecing songs together? I just was bored messing with an old version of traktor this morning and I had a couple questions sorry for the long post and grammer im tired :P
