Yow-Hann Lee - Software Happens

I would suggest the Music Brainz MP3 tagging approach to take into concern: http://musicbrainz.org/

Great answer Robert. You nailed the quick and dirty approach with the metadata tags. And you also identified one of the cons with this approach by providing a uniform channel (musicbrainz) in which ppl do this.

Since there is a lack of uniformity with the tags in the general case, can you think of a more involved approach? One of the more involved approaches that I had in mind I haven't seen applied in a program. There are also cons with the approach in mind. But seeing as this is a design question, the aim is to see how someone approaches a problem (i.e. are they methodical? do they think through the problem carefully, come up with possbilities, list pros/cons of them and tie everything together for a solution?)
