If everything is tagged properly and you still have issues with Spotlight (it's buggy), then start iTunes and hold down the OPTION key which will allow you to create a new library.

This will be a temporary library so put it wherever you want it.

Next go to iTunes prefs and tell it not to move your music - leaves it on its original drive when added to iTunes.

Now drag all the music from the Vibez into this iTunes library.

Find the songs you want in the iTunes library and when deleting them, tell it to remove them from disk as well.
