iPod / Dell Pocket DJ - question

[xxxmx]

i'm in the mood to buy one and would like some input.

i would prefer the Dell as there is no way in hell i'm using iTunes.

so here's the thing: i read through the online user guide and it mentions that you cannot load pirated music. what is considered pirated music? i've got all of my CDs uploaded onto my computer, can i load those files? can i load the 5 gigs of stevie boots? what (if any) problems have you had with the Dell DJ? i use Windows Media Player, do i have to convert files or push them through a different program?

all raves/bashes welcome...
