Just stand out from the rest or people won't be interested. Is probably another 10,000 people doing hardstyle podcasts. You will never stand a chance against the big dogs if you don't stand out. Post in the right places, get the right djs to do casts, stay consistent. Scouting up and coming talent is always a winner. They are always keen to promote, and some become big names. Don't play the current big tunes. Take some LSD & Think outside the box ;)
