Playlist copier
I have a pocket pc that I use to listen to music. I like to change up what i'm listening to while I'm using PocketMusic - which is excellent.
So I wrote a little app to take whatever playlists I've created on my computer and copy them over to my sd card for use on the go.
Things that I will do if I figure it out - try to go around having to take sd card out and use usb writer . see if there is someway to just go through active sync.
Since I didn't see this trivial app out there - I created it.
Here you go.
