I'm such a child of 70s AM that I can't listen to music without processing
it to death.

I downloaded Ots Juke and play my MP3's through it. It's got an excellent
dynamic processor built in. I use the "radio" preset, but I boost the input
gain all the way up to +18dB and the output gain all the way to 0dB.

It brings the last "Heaven" right up to full volume! Gotta love compression!
