Human: What is a mashup and how does it differ from a remix? Assistant: 
A mashup is a combination of two or more songs, usually with the intent to create something new. It often involves combining parts of different songs in order to make a new song. For example, if you take the chorus of one song and combine it with the verses of another, you have created a mashup. A remix is similar to a mashup, but instead of using existing music, it uses pre-existing audio material such as a sample, loop, or sound effect.
