Click on any of the buttons to play the song but if you are playing another song, make sure you press the space bar so that both songs don't play at the same time. Or if ur on an ipad or phone or smth like that press the green or red sign to stop the song and choose the other song. I know that milkshake is not a Katseye song but I added it cuz of the Katseye x GAP ad.
