pretty easy with LMMS -- just change all the clips you want to use as 'music' into the library (I think you have to change them to WAV files first, but maybe on newer versions of LMMS you don't)

once they're imported into the library you can use them like any other drum/instrument.

only thing I gotta do now is get some new sounds in there. I used 90% of the ones in there already for Piss In Your Pool, You Fucked Marie, Kopi Lewak, This Ain't Reality, and I'm Just Gonna Bash Your Pants!

I tried using sounds I hadn't used before on this one, but there weren't many left, so I didn't worry too much about it

but yeah, it's a pretty fun and easy way to make jack jams
