Goat Simulator

From the start area, looking at the BAAA machine, go through the arch to the road. Follow the road to the right and at the T intersection go left. and then an immediate right up the hill. You will pas the police station on your left and the very next building on the left on the corner is the burger joint. In the front lot of the burger joint is a couple of npc's looking at a fire in a barrel and an suv. When you walk up to them you will get a message that these guys need a boom box.

Now turn around and go back down the road in front of the police station and take the left just before you go down the hill. On the second building on the right there will be an open door. Inside this building will be some exercise equipment and the windows will say "aerobics center". Enter and turn left. Against the wall straight ahead will be a boom box. Lick it and take it back to the people at the burger joint. It should automatically place the boom box when you are in the right place and award you the achievement.

Also, when I played this on the One version, out by one of the trophies that is on the dock. There are a couple of sun umbrellas and another boom box here. I am sure there are others, I just happened to find this one while getting the trophies and I am not sure if it is in the same place on the 360.

When you spawn choose any of the animals to be, go towards into the town where all the buildings are, on the left-hand side of the town you will find a chicken fast food type place with 3 people outside, if you go next to the people they will give you a mission to get them a boom box. The boom box can be found by heading south from the chicken place, then take your first left and the gym is on the right-hand side of the road about half way up the street. Lick the boom box to pick it up and take it back to the people and as soon as you get back to the people your achievement will pop.

If you need any more help or would like a video to direct you I will leave my video guide below.
