This is a stab in the dark from me!! might be better from someon who uses iTunes full time , I stopped using it last year (Cant stand the PC version, nasty software IMHO)
My Guess is you may need to convert the tunes to mp3 for your kill tracker? As iTunes woudl be AAC? Not sure if your tracker supports that. But as far as I know itunes can allow you to code in mp3????
