Its been years, but the jist of it is that we couldn't get bit-for-bit comparisons at all after the zip and unzip routine. That's why those Audio specialty compression programs got started into existence in the first place. Along the way, they learned how to even make the filesizes smaller for audio .wav files than zip can do.

Flac is good, too.

But again, you don't need to do all that at all.

I've submitted those 128kbps mp3 files using the LAME encoder to pgmusic during the beta tests for years. It is plenty good enough for this kind of work, plus the advantage of direct webstreaming means the developers, whom are already as busy as can be, don't have to jump through hoops of fire in order to just hear the example.
