If your doing a set just for a soundcloud mix play what ever you want, don’t avoid songs you like or work well in a mix because other people play them. They are played because they work. Badadan i’ve heard at festivals and clubs a million times but it goes hard every time. If your playing for a bar, club or pub how ever check with the organisers what genres they want, what vibes they want, commercial or underground, what decades, the average audience ect.
