You're a brave man to bring this up again.
I also have Tool and DT CD's and have them in my CD changer in the car where my kids and I can listen to them at the intended volume. It is music that makes my heart go faster, not always a good thing at my age.
For me, personally, I am OK with it not being on AM's list since AM offers non-metal prog. and suits my work atmosphere just fine since that's when I listen to it. But then every once in a while we will hear OSI or LTE and I just crank it up!!
