OK - I have the general principle. But how do I get the best use from them? Can I select all the music in all the libraries, for instance, and use them as a random play list for a party? Can I use then to index my photos?

I am pretty technical, but more used to good old folders and, believe it or not, CLI on Unix! So, don't spare the technical advice or the rod to tell me what a numpty I am.

Any advice, anecdotes or required reading lists gratefully accepted.

Cheers
