How do you rotate between Opeth albums?

i like to spread as many opeth albums as i can onto one disc (usually about 6) and I dont have an ipod/mp3 player so thats teh best i can do. I then just stick it on random and that way I dont ever get bored of hearing the same stuff. (I wouldn't with Opeth anyways)

Oh, by the way I do own all the albums so Im not ripping the band off in any way
