Great mash up! This takes me back to my early days of making music with OctaMED on my Amiga, when all I had was an 8-bit sampling cartridge and a large collection of funk and jazz CD's. I'm pretty sure I had that exact flute riff sampled off of something. You can have tons of fun putting music together like this, makes me want to start doing it again.
Don't know if you've ever tried this Beepster, but a great technique when you're making this kind of music is to take a drum loop and split it up into 8 equal sized slices (making sure it's all matched to your project tempo etc). Then you can combine those 8 slices in any order you like to make completely new beats. You end up with some pretty funky rhythms you would never have come across otherwise. We used to make drum 'n' bass tracks like this in the early 90's.
