I have a ever growing iTunes library, but sometimes when importing stuff, the ID3 tags go all wrong, or in the in Japanese/Non-English Characters. So like many geeks I hate having to mess with each ID3 tag individualy even if iTunes makes it easy. Solution CDDB and a little script from dougscripts.co. You simply go to the playlist, run the first script which searches CDDB to find the album your playing, then you run the second script that then copies the page details and puts them in your ID3 tags. Voila! your library is nice and perfectly formed.
