i need tagcloud for sorting my music

in the last years i spent realy much time on checking out new and old music, tagging and sorting it; manually in folder systems sorted by labels and such and some times, when it gets me, with itunes. until now, i couldn’t find a system which work for me. today, i restarted sorting my music into itunes and so i asked me:

1. why itunes doesn’t support multiple tags and a visualisation like tag clouds on last.fm?

2. why not hiding data we don’t want to see and hear actually?

3. why pimp not up itunes with more relative neural visualisations of the local contens based on your tags with wikipedia informations about the insides, the decades, similar movements, label mailings, videos, new music etc.

does anybody know something about projects in this direction like putting last.fm into itunes as plugin? or putting itunes into last.fm? :)
