John that's fine if you want to just make a few tweaks and changes ....but to really make the style your own you have to dig in
and RE-Record some tracks to you liking, eg: bass line, drums, percussion, brass, etc, to give it that custom treatment and "originality" that makes the song stand out and come alive.
It's not that difficult and you get a real sense of accomplishment.
After all you paying for these features within why not utilize them?
