That's odd. I almost always get 40-60% compression using FLAC 1.1.

Not surprisingly classical and ambient music generally compresses the most and
electronic the least (can't speak for other genres).

I can support this. Close to 50% is typical. After FLACing my 300
odd CDs (highly varied collection of material and 'full' and less
'full' discs) I get a rough compression of 3CDs/GB.

Me three. I get around 50%, some more, some less.
For a secret, I set flac to --best
which takes longer to compress, gets a little better compression
and takes no longer to decompress.

In general, it seems to take lots longer to yield a very small amount if
additional compression. Maybe two or three times longer for a few percent.
Which would not be worthwhile, but my computer was doing nothing
anyway, so I let it run over night compressing its little brain out.

If the CPU cost anything, it probably would not be worth doing, as
disk space is nearly free.
