Very good point, I didn't think of that. Quite a shame to limit the RVA2 
tag to 6 dB gain only.

That should be easy to do. Just convert the Sound Check value to dB, add 
the RVA value and convert it back. I could write a patch for that, but 
I'll need some test files as I don't use any RVA tags myself. I guess I 
can use normalize to create some RVA2 tags.

This will imply that gnupod will stop using setting Volume iTunesDB 
attribute, except when a value is already found in the iTunesDB (by 
tunes2pod.pl) or am I missing something?
