Script to Create Playlists from Juice

In this post, I talk about my challenges of finding an application to use with my Sansa and podcasts. Well, I settled on Juice. But, I still had an issue with playlists. Juice allows you to launch a program after a file is downloaded, so I decided to write a script to do what I want. I thought I would post it here just in case anyone else is looking to do the same thing.

Here are the steps to get the script to work with Juice (I’m going to assume you already have downloaded Juice, installed it, and have several podcasts actively downloading.  I have Juice 2.2.  If you have a different version, the instructions may be a bit different.):

  1. Download the script (right-click this link and choose save target as.  Remember where you save the file)
  2. Launch Juice
  3. Go to File –> Preferences
  4. Go to the Advanced Tab
  5. Check the “Run this command after each download” checkbox
  6. In the text box, enter the following text (making the correct replacements, of course):  BuildPlaylist.vbs “” “%n” “%f”
  7. PathToVBS is the location you saved the vbs to when you downloaded it.
  8. PathToPlaylistFIles is probably something like c:Documents and SettingsMy DocumentsMy MusicMy Playlists
  9. You want to enclose each item in ” (those are double quote marks).  That way, Windows won’t barf on spaces
  10. Click the Save button

That’s it.  If you need some help, just let me know.  E-mail me at matt (at)

[Update 2012-12-19 06:59:42] In getting ready to migrate my website, I found some broken links.  Fixed the link to the script.
