Nice, I'm sure a lot of people would be interested in trying this.

But talking to myself, I'm disgusted with all of this, so I'm just maintaining my mess in its current state for now.

Still, I like to see such solution, and I'd be really interested in a counter article to what I wrote dealing with each issue. Even if at the end, I will likely not use the given solution.

About the regex search, I'm not sure that's really the solution to the "textual problem". As mentioned in the article, the music content retrieval system is in my opinion the future. Echonest and similar services are trying to achieve something like this. Looking for one artist isn't really what you actually want most of the time. It's likely you are looking for good music, and just want to listen to things who sound "like this".

Sorry-- I was unclear. The regex is not for organization. It's just an easy and flexible way to browse subsets of your library, like smart playlists in iTunes, but more powerful.

I was actually talking about browsing. The musical content analysis has the goal to provide new ways of representing your music, and browse it.
