Pop Bastard? What, like Pop Bitch?
No, like bastard pop.
Bastard pop?
Yeah, bastard pop. Bootlegs, mash-ups, ploppers - that kind of thing.
Bootlegs?
Strictly, any kind of illegal recording (in the music world, at least) from taping a live concert to making counterfeit CDs. But it's normally used to refer to a mash-up of some kind (legal or not) especially a plopper.
So a mash-up is..?
A mix of two or more tracks (and/or other samples) to make a new one.
