So, being a programmer on paternity leave, I figured I'd learn Applescript and automate the whole process. I wrote a simple script that will copy the highlighted songs in iTunes--automagically converting them to MP3 on-the-fly if needed--to the desired playlist on the Sweetpea3. It wipes all MP3s on the chosen playlist before it copies the new ones. If you've changed the name of your Sweetpea3 to something other than "SWEETPEA3", you're SOL because this little script hardcodes this device name.
Give it a go if you're a Mac user and a Sweetpea3 owner. Drop me a line and let me know how you like it.
My two cents on Applescript is that it's the opposite of Perl: it's easy to read and bloody impossible to write. It's massively frustrating especially if you actually know anything about computers, like file paths, or heaven forbid Unix. So coming from a Java, SQL and Unix background, I found Applescript a real nightmare. But I was able to bang out the core of this script over the course of a half dozen baby naps.
Here's the source. Paste this into the Script Editor application and save it as an "Application Bundle" in your Library/Scripts folder. Then you can access it in the little scripts icon on the toolbar.
It's not terribly elegant, but it makes life easier. 'Nuff said.
