copy each track as many times as needed until it fills up about 7 minutes.
Then just use the mute tool 2 jam and record that or take notes... by the end u'll sure have some ideias of who the all thing works better how should some sounds come in (direct or fade in), what should come first and last, etc.... it's a bit of trial and error, .. every now and then go 4 a cuppa, so u gain some distance and comeback with fresh ears. turn of the PC's screen and press play (so u don't get any info except sound, like a normal listener) that should also render ya with some ideias, corrections etc... try 2 stick with normal guideliness but avoid the formula! ;)
