Unfortunately, Zip isn't going to get you 50% compression on audio files. There are some options in Zip, but whoever receives the file must have a version of WinZip/7Zip/etc capable of decoding those options. And Zip is really designed for general purpose, not audio-specific.

You would have to use a lossless CODEC instead - maybe FLAC or APE (Monkey's Audio), which are optimized for audio. But then, of course you would need the drive space to download the files, and then take the time and additional drive space to decompress them.
