Certain part of song

So, some of you may not like techno, but I do. I have a long block of techno, but there is only one particular part of the block that i want. what can i do?

is it in itunes? click on it and get info. theres some preference under ther where you can change the start and stop time.

If you have soundtrack or garageband you can open it in either of those programs and cut out the parts of the song you dont want. Then convert it back into itunes and tada you have your favorite section
