MP3Gain - getting overall library averages Options

[BFG]

I have a quick MP3Gain question, for those familiar with the tool.
I know how to use Track Analysis, Album Analysis, etc. to get overall "sounds like" decibel levels for a given track or album.

But I'm interested in seeing what the overall "sounds like" level for my entire pre-ReplayGain library is. The only way I know to do that is to copy my entire collection into a single folder, treat it as an album, and do an Album Analysis. Is there a quicker way?

(I'm doing this because, rather than using the recommended dB levels of 83 or 89, I'd simply like to move everything to the "average" for my collection.)

Hmm, good points DVDdoug. I suspect the fact that avoiding clipping typically means reducing volume is the reason the most recent EBU recommendation is 80dB (-23 LUFS). The issue I see is that, if you reduce volume enough to avoid all clipping, you'll destroy the dynamic range in the process.

I suppose the best thing to do would be for me just to listen to several songs and decide if 89dB works for me, or if I need to set it somewhere else. Thanks.
