I don't think they have a definition of art like that; rather they are frustrated that abstract art (or classical music, or opera) is given a place of honor in place of art they themselves enjoy.

Why is fine art given public monies, and sound systems are not? More people get enjoyment from sound systems than will ever even know that piece of art exists. And their enjoyment of sound systems is exactly about conveying a feeling or a vibe.

NB: I hate sound system music; but I am well aware that it is way more popular than any so-called fine art.
