I think i found a bug on a particular directory of my MP3 tree (album "Absolution" by Muse), which I scanned with mp3gain.

I later re-launched mp3gain on this directory, clicked "Album gain", and it started re-scanning the directory, as if asked to ignore the tags (and that option was *not* enabled)

Now, this is most of the time benign, but ignoring the tags can be a real problem : if the album had been track-gained, doing an album-analysis later on would *loose* the original differences between the album tracks.

I've tried again, re-scanned the directory, to be sure it really had been scanned by mp3gain, and the be bug was still there : at the next 'album analysis', the tags werent used and mp3gain started analysing again..
On all my other directories this doesnt happen.

I'll try doing that on a re-rip of the album, with a different encoder if I can, to see what might be causing this..

The only special thing I see with this album, is it starts with a mostly intro track, which is 16dB lower than the rest of the album. Could this lead mp3gain to assume the album analysis needs to be done over ?
