You need 2 tools to update the list automatically. ShoutScraper and Relax
First set up ShoutScraper. Shoutscraper will logon to shoutcast.com and download the top 20 channels for each genre you set up. By default it will do this every hour (BAD!!!).
IMPORTANT STUFF -> Shoutcast has put on a filter that only allows you to download links for 600 channels every 24 hours. So lets say you have 30 categories with 20 channels per category (30 x 20 = 600), every hour you would be requesting 600 channels... after the first hour you would be generating bad links cause you would be blocked. What I did is I set Shoutscraper to scan 15 categories for the top 20 channels every 12 hours (15 x 20 x 2 times a day = 600). This will keep me at or under the 600 requests per day.
When the program is run it puts all the .sc files neatley into it's own subdirectory on your pc. I made a directory on my pc's d: to hold the subdirectories which looks something like this:
d:
+shoutcast
--+Top40
------example1.sc
------example2.sc
--+Alternative
------example1.sc
------example2.sc
an so forth....
The program will automatically generate the subdirectories and the .sc files you just tell it where to put them in my case it would be d:/shoutcast/
After you get that up and running configure relax to share the shoutcast folder (d:/shoutcast in my case) with your xbox then make a link in your XBMP config.xml file, mine looks like this:
<share>
<name>Internet Radio (SHOUTcast)</name>
<url>d:\shoutscast@192.168.1.2</url>
<cachesize>256</cachesize>
</share>
That's it!
Reboot your XBMP and listen to your 300 new radio stations
There are other stuff that you have to customize for shoutscraper, like installing it as a service, but you can real the documentation that comes with the porgram.
Also I can't find the link anymore for shoutscraper on xbox-scene's tools page but the file is still available
