The opposite happened with music from a style they didn't like.
When they tasted the same ice-cream while listening to music from a genre they didn't like, they rated gelato as more bitter and less pleasant.
"We tried to measure the hedonistic level of how people were feeling when they listened to the music, and we found out that disliked music decreased the pleasantness ratings of all the chocolate gelati," Mr Grazioli, from Giapo Haute Ice Cream in Queen St, said.
"These findings give an idea that we eat with our brain before we eat with our tastebuds.
"It's the first study in the world to show that taste perception actually changes with different music."
Because music and taste was so subjective, Mr Grazioli said it would be difficult to incorporate the research into his store.
"It's a little bit more complicated than that because we are all different, and you like music that probably I don't like and so does everyone else," he said.
"This study actually tells us that for whatever you like in terms of music, if I give you something you may like that something a little bit more because probably your brain is at ease."
Noises and settings can trigger individual emotions and memories, and they were different for everyone, he said.
