I tend to agree, but:

Pro EXTM3U:
- Playlists are convenient for searching filenames.
- For searching the tags, we need some index format anyway, so
  why not extend the one we use for filenames
- The winamp playlist format seems to be wide spread
  <http://www.google.com/search?q=%23EXTM3U> finds several
  different mp3 player and perl modules to handle these comments.
- We can use 3rd party software (e.g. winamp) to crate the index.
- We can use the index in 3rd party software as well.

Contra:
- We clutter playlists (in a backward compatible way).
- Not all of the tag info are available in the EXTM3U comment.
  (But can be extended a 2nd time with some other comment, if
  realy needed.)
- A custom index format could be designed that is esier to be parsed.
