low technology

like many people I have a little portable stereo. It's nice to have, I use it mostly at the gym, makes running on a treadmill seem less dull than it is.

Here is my problem: I have a wide range of a lack of taste, and my music sources are from CD's all over-- classical, oldies, bossa nova, whatever. And every one of these songs had a different engineer determining the audio level of the song. This means the agnus dei from a recording of the faure requiem needs to be turned up all the way, but unfortunately, the next song in the queue of the player (a sansa 250 which I can't control all that well in terms of order of songs) is the motwon shoop shoop song, and blasts my eardrums into dust unless i remember to quickly grab it and turn it way down.

In this digital age, would it be so hard to look at all those 1's and zeros of each song's files and allow me to set a preferred volume level on my player that would be applied to all songs no matter what the original engineer did to muck it up?
