iPod playlist question

[Spanky McDuck]

I have about a dozen pod casts I listen to at work, other than KATG they are mostly science, astronomy, etc. The play list I have is basically all unheard pod casts in the order received. This works fine, but I want more. :-)

Anyone know of a way to intermix random music between pod casts? Is there a program that might could make a play list from combining two play lists?

I work part time in a factory on a simple production line. Very mind numbing but it's hard to take the time to change play lists or such while working (in other words, the bosses don't want to see us standing there 'playing with our toys' when we should be working :-))

TIA
