PodWriter is a (now Cocoa & Objective-C, was Java) application to display notes on your iPod.
What’s new in v2.2b1:
Adds some basic mp3 transfer functions. It’s not anywhere near finished, but here’s a look at it. Choose List Music from the mp3s menu and then make sure you select your destination folder. Once I figure out how to read mp3 tags correctly, it’ll get some more functions and a nicer appearance (function is more important than looks).
