As plain details, they might just as well been left out. Actually, I can't even really see where that part with the slots moves to in robot mode: it seems like those parts fold into the rear of his legs? The legs are the parts with the most available bulk to them to contain something like electronics: his main torso needs to contain a maximum of three casettes, so that will not have much available space.
Adding an MP3 player isn't very expensive, and the (pretty hefty) retail price for this item would definitely allow for something extra. The attachment below is the relevant detail, taken from the Amazon.jp site.
The top part down to the blue is actually the bottom of Soundwave's foot. The rest flips to form the kibble on the side of his leg. I made an animation that shows that, check old post for that.
Soundwave's feet are still kind of a mystery to me, because when you look at them from the front, they look like they could either split apart or rotate the toes in some way. If you look at the second pic, you'll see that his feet have a black crack along the inner sides.
