okey-dokey ... thanx all for reminding me of this point, cos i probably
don't think i do trust my ears enough -

but don't worry, i've no choice but to use my ears first - my skills at
the technical side of stuff (such as reading an audio analysis
spectrum/curve/whatever) are pretty non-existent :)

JAPA looks like the tool to give me a bit of Intuitition, though - i
guess it would be a good idea to run a bunch of stuff through it, just
so i can see how a well-mixed track looks as opposed to a bad mix, and
where the different instruments lie on the spectrum.
