Hi,

I got some ideas to manage my collection. It could be usefull to have some group of custom tags:
- country : US, Spain, France, ...
- dance : rock, Cuban salsa, Puerto Rican salsa, west coast swing, waltz, ...
- instruments : guitar, piano, ...
and possibility to make groups of custom tags
And if there are existing website to synchronize with them.

For id3v.2 there are specifications about tags/frames. So that can't be done. Don't know about the other codecs.

Greetings

I believed we could add custom fields in ID3v2 so no standard data.
otherwise, it could be managed by the Amarok DB or with a metadata file containing missing informations.
