I think you should just play what you like. Play it how you think it should be heard best. If that involves playing mixture of styles, a balance of soft/hard or uplfting/dark or whateever, then that is your prefecnce.

I personally like to either play uplifting/hard trance or hard trance/hard style. I just feel too much of the same genre can be a bit boring so having the best of those genres put together I feel is best.

But I don' think you should start play other genres just because your worried that people won't like you for playing just one genre. Just play what you think is the best receipe for good music!

Hopefully your listeners will agree!
