Add music index

I have edited the config.xml file in an attempt to add a new music index. I added an entry
. I restarted the server and rebuilt the indexes, however my index does not show up. Only the standard ones. what am I doing wrong?

Found I needed to recreate the library.

It is going to be hard to tell you what is wrong without seeing the changes you did to config.xml. One thing that you should keep mind is that the new index will only show if you re-create the library.
