lazyweb- metadata, tagging, tag clouds, and audio files

[metaphorge]

I'd like to be able to include a list of FlickR/lastfm/etc.-style tags as metadata for my audio files and then use this information to be able to sort tracks, preferably in iTunes.

(In other words, I'd like to, for example, tag a song as "angry, new wave, erotic, fish" and then be able to sort based on any or all of the tags in order to assemble playlists.)

Assigning a singular 'genre' to a song seems far too limiting.

Does anyone know of software or plug-ins that can do this? ID3v2 is flexible enough to contain this type of data, but I'm unaware of anyone who's written an implementation of it, either as a stand-alone application or as a plug-in for music players.

Is this question clear as mud? If so here's an article on the kind of metadata tagging I'm talking about that might clarify my question.

(I realize that I could use the 'comments' or 'category' fields in an ID3v2 tag to do this, and then use iTunes smart playlist searching features to do this, but I'd like a more dedicated and elegant solution that treats each tag in a list of tags as separate data. Being able to work with tag clouds (here's an example) would be an additional bonus.)

the iTunes library writes a standard XML document.

easiest solution would likely be to import the XML into a spreadsheet or database and track the tags there (since you could then import tag data from whatever your preferred source is) and use it to build the lists, which can then be exported as standard .pls files for use in iTunes

I had a bunch of problems using my Iriver music player in conjunction with my mac last year. I recently found some software that analyzes tag data and translates it to the music player. I don't know if it wold help butheres a link to their forum, the guys that developped it are super cool and helpful, they could possibly give you suggestions on how to use the ID3v2 info to your advantage:
