If you play most modern CDs in a PC using Windows Media Player 7, the program will show the 'Artist Name' and 'Track Title'

No big deal there.

However, when I put in 'Rigs of Time - The Best of Martin Carthy' media player tells me that I'm listening to Carthy's 'Signs of Life'?!?

This is not an important question, but I'm curious.

If anyone knows how these things work, or could point me to a site that explains, I would be grateful.

Thank you

Terry
