Pizza is a physical good, Music is an informational good - there is a variable cost associated with taking one piece of pizza and turning it into two pieces - there is no (or at least a very limited) variable cost in duplicating a piece of information, like music. Hence, although you can steal both music and pizza, the physical ramifications of doing so are different. (disclaimer: I'm not trying to say stealing music is "less" bad than stealing pizza, but rather am just trying to state the differences between the two)
