It would just be another metadata! It's great!
You just ask for the metadata named: 

sql:SELECT filename, size FROM DIR RECURSIVE WHERE id3:artist = "Britney Spears" AND NOT id3:album contains "Oops!"

on a directory. And after the query optimizers, the recursive id3 decoding 
of all files and the database query have run you'll get back the result as 
an xml string that you just have to parse to get the list of files to display.

It's even better when it starts following cross-method uri-symlinks to 
download and id3-decode mp3s from the web. Imagine it indexing all the 
files at using that simple metadata request. Its the best thing 
since monikers!
