the managers that use a database have an exceptionally hard time managing it all without slowing my system to a crawl

This one doesn't. To a point. How many MP3s are you talking about? The "All Tracks" list can start to get a little slow past about 10,000 tunes (from memory).

The other views are superbly fast.

Glad to see it doesn't.

It does, but it doesn't force you to.
