I was wondering if anyone around these boards knew about this program i heard of and if it really exists.

For a regular ipod, lets say 5th gen video or w/e, I hear that there was a program you could DL to your Ipod that would allow you to kind of fade tracks into one another. Not just play them gaplessly (i know they already do that) but rather kinda fade out of one and into another. It's kinda a werid request and i'm not even ure the ipod can do this but If anyone has any software or solutions kinda related to this questions, please post 'em here.
