All in one solutions SUCK. If you want an all in one solution buy a Mac. I don't want MMC to do a whole lot of different **** because one guy on the forum wants it, because it will make the whole program bigger and slower and with all respect to the MMC guys, MMC will never do these specialized tasks as well as a specialized software meant to do it. If you have a problem with volume levels then get MP3gain and run the darn thing, if that is too much work for you, how in the hell did you wire a computer into your car. Sorry for being an *** but geez.
