As illustrated in
Personal Anything Database?, I was able to adapt the program and write a script to collect album data from the old AllMusic site. The hard part (for me) was writing the script. I haven't had the stomach for attempting to redo it for the new site, which is substantially different. Modifying the program was a bit tedious, but not difficult. It involves using standard fields for similar data elements and adding a few custom fields, using a custom language file to change captions to match their new purpose, and creating a skin to display the results.
At this point, I suspect the easiest route to a working script would be to adapt
Ivek's AllMovie script to work on the AllMusic site. They're not exactly the same, of course, but the basic structure appears to be similar. Although I haven't tried it, my database and skin should work in version 1.0.x of the program. The language file would have to be redone.
