Linux Question

I'm off work today on medical leave, and working on the Penguicon program book. I use my Ubuntu Linux desktop computer for web browsing, instant messages, music-- everything but games and graphic design software. I dropped the folder "My Music" into Totem Music Player so that it would queue up all the music files in my entire collection to play for me randomly while I lie in bed recuperating and working on the program book on a laptop. I liked one song in particular and went to find it in my filesystem. It was nowhere to be found by browsing, but turned up with the "Find File" feature:

I right clicked it and chose "Open Containing Folder":

It's contained in home: Music: Soundtracks: Ghost In The Shell. So I clicked the Soundtracks folder.

The Ghost In The Shell folder is not visible in the folder that the computer says it's in. Why?
