"My Directories" ships in every copy of Sparks! with two undeletable directories: "BlogMatrix Radio Stations" and "Podcast Directory". These files are dynamically loaded (using OPML) whenever Sparks! is started.

The total number of radio stations we have access to is pretty big — it's probably two or three megabytes of data. To avoid making you download a lot of data you don't need we've split the directory up by geographical region. Under the "BlogMatrix Radio Stations" directory, you'll see six world icons for Africa, Asia, Europe, Middle East, North America, and Oceania. Double-click on these to get radio stations list for these regions.
