Everybody understands that the pleasure of ice cream is different from listening to music, but they don't understand that pleasure includes both "exciting" pleasures and "all normal non-painful experiences of life."
The pleasure that comes from ice cream is different because the part of the body involved, and perhaps the jolt of sugar has a greater intensity...but perhaps doesn't last as long as the pleasure of music (enjoyable to the ears and perhaps tied to happy memories). Yet, another thing to think about is that the underlying "state of being pleased" is actually the same for both of these, therefore you could substitute one for the other (if necessary).
