Musical genre. Involves cutting and pasting samples and loops from two or more popular tracks to form a new track, often forming a suprisingly catchy new tune. Not as complex as remixed music. There are a number of bedroom djs who create moderate quality mashups.

The more different the genres of the source tunes, the more effective the mashup.
You downloaded the Run DMC vs Tom Petty mashup? DJBC is an artist, man.
