This is something that is sorely missing in the software for all those people (including myself) that have a Network Walkman (I have the NW-HD3). It's ridiculous to try to organize the files on a 20 gig machine with only a tiny window, and very little sorting options. I'm sure I've got duplicate songs all over HD3. Plus, trying to organize and rename groups, artists, and other attributes (so they have a better sort, etc) is just pathetic. The window should be as large as, if not larger, than the "My Library" window. Sony needs to take a page from Windows Media Player regarding the ability to organize music. It should also recognize "The" in the Artists, such as "The Rolling Stones", and put them under "R", instead of "T". Such a simple thing to do in code. It just shows laziness on the part of Sony. Sorry for the rant, but c'mon Sony, get your act together!
