Arduino to play mp3 through macbook pro

Hi all. I am very new to Arduino and all that it has to offer but so far its been great. My latest project consists of me using conductive ink on different textures and surfaces then linking it up to the Arduino uno to create sounds [which I would like to come straight from the laptop speaker]

Any help would be great, also please guys let me know if there is an easier way to produce sound using conductive ink on different surfaces.

Thanks in advance!
