For the record, FLAC is lossless: going wav -> flac -> wav recreate the
exact same file, byte by byte.

I can see a few cases where smaller size for the same data is better: it
use less storage (obviously), transfer faster over internet/over other
networks, less memory bandwidth with hardware decoder (granted FLAC
hardware decoder are not that common). I see no advantage, when possible,
to not compress stuff, especially when the process is very fast in both
directions. Processing power is inexpensive too :)

There is something to say for playing an original file when it's almost universally playable by hardware at the binary level :)
