The definition of art is unclear and every interpretation I've read boils down to making art a subjective matter. Borrowing from ye olde Wikipedia:
"Art is the product or process of deliberately arranging items (often with symbolic significance) in a way that influences and affects one or more of the senses, emotions, and intellect."
Therefore a cup of coffee can be art since it engages the senses (taste and smell) as well as emotions (relaxing). Only elitists harp about something having to be intellectually engaging to be considered art. I've seen plenty of works of art that are purposely repulsive and/or meant to engage very base emotions (fear, anger, hate, lust) but are in no way intellectually stimulating.
