Aw, heck, I'm not talking about anything complicated related to the musical content. I'm just talking about a linear alteration in the amount of loudnes boost relative to the volume. Just so that you get more static loudness when the volume is low (so you can still hear the bass over the road noise) and less static loudness when the volume is high (so it doesn't sound boomy and you don't blow your speakers).
