Can you elaborate?

Are you in effect creating a playlist with the "best" parts of songs.

Exactly what hardware are you using for this? "Classic" iPod with a custom firmware like Rockbox? Or iPhone/iPodTouch?

I just used some of the 'classic' built in features. Nothing too fancy, just loop over whatever part of the song you choose however many times you choose.
