I don't know if it counts as a super power because there are actual people with this condition but I'd want synaesthesia which is also known as having merged senses.

People with synaesthesia experience the senses that the rest of us feel: as in sight, hearing, taste, touch and smell as a fusion of sensations. For example, they will see colours and shapes associated with the music they listen to.

The reason why I think this would be cool to have is because I like to think of myself as a creative person. As a creative person who loves or at least has an appreciation for art forms like music, visual art, cooking and food, and textures I think to have synaesthesia would make it easier and more wonderful to incorporate all of these art forms together.
