Well "Discogs" is already an option with the version of Mp3tag I am using. I personally have found it to be quite unreliable, along with the "freedb" option, so I generally stick with the "amazon.com" option.
I found three differant scripts for Discogs in that forum:
/t/1992/1 by dano
/t/4346/1 by Ydope
/t/6191/1 by dano
I take it that the bottom one is the most recent / the best?
I also noticed a last.fm script which I like the look of - another site I use a lot.
I will try out the MusicBrainz script by Zeef which you so kindly mentioned and see what that is like.
All the same, I think a Wikipedia Web Source Script would be awesome!
Thanks for getting back to me dano...
