I'm trying to avoid overloading my Squeezebox touch. Most of my files were encoded at -8, but for the minimal extra space, I'd like them at -6. Is this possible, withough losing tag information, etc. I.E can I select the whole library and convert all the flacs it finds at -8 to -6 (Note, some are -6 already, will it just skip these, or will it try re-encoding them too?).

I'm assuming it will take a long long time...
