The xx - islands
REM - Texarkana
Hayley westernra - pokarekare ana
radiohead - subterranean homesick alien
all quite different these songs but give a broad test I think.
If you have no problem with hard disc space and you want 'WAV like' rips but with album tags etc then AIFF is good. I can't understand why any music should be compressed today when ~900 albums could fit on a £50 500GB hard disc.
