iTunes 4

Some notes regarding iTunes 4:

The existing Winamp plugins for AAC/MP4 files (FAAD) don't play the preview streams from Apple's Music Store, or AAC files encoded with iTunes. Quicktime 6.2 for Windows, when it arrives, probably will. is the starting point for the Music Store, but the browseStore part seems to be encrypted.

This is why you need to password-protect your shared library.
