I need to be able to bulk rename tunes -- I need to get a bunch from a friend but they aren't saved in a playlist, so I can only get them by having him do a full backup and importing that. If it was possible for me to bulk rename I could append his name to all the charts I got from him, then keep them in a separate playlist to keep things tidier. But I can't.

Or, if I could even sort the list of songs by the date of import.

There are a few basic file-management like features that would make the software a lot more useful.
