Yes, my script is a bit complicated to install if you use it for the first time. Instruction is given in the strating post of this thread and in various questions and answers in it. If you still have questions about it, feel free to ask.
The artwork problem is sloved. Seem to have been a server problem at discogs.com yesterday.
But there should be no fields "tagged very weird with silly little comments". What do you mean by that? Did you solve it?
Nice Forum. I think I will register since I'm also very interested in the oldschool of electronic music. But for question about the script, please post a link there to this thread or/and the one for dano's script. All the questions there have been discussed here in the forum serveral times. It's a bit ineffective to explain things at different places if all could come together in one place. So I would prefer to answere questions here.
I see your forum is a lot about DJ Sets. Maybe another web script I have done is very interessting for you. It is form MixesDB.com and gets basic tags like ARTIST, ALBUMARTIST, ALBUM, TITLE, YEAR, GENRE and also Coverartwork and a Tracklist if available at MixesDB.com.
The UK sound is a bit underrepresented at MixesDB.com, but it's growing.
