A wild project appears!
Lately I’ve been working on a new project to sync music with my Sansa e260. Unsatisfied with manually moving files on and off of the tiny flash drive, I began work on an application to manage playlists and sync them for me. I’ve gotten it to the point where it scans my music collection, allows me to create playlists, and syncs those playlists with any directory I specify. In the future, I plan on implementing removable device recognition and cover attachment and resizing. It also currently only functions as a command-line client, but there are plans to develop a GUI frontend for it once the base library is stable enough.
Anyway, the project page is available behind the link on the right (or right here).
