I want to give you folks a heads up. I've added a couple of new fields, as I've learned a little bit more about AMG track, artist, and album IDs.
Currently amg.pl wants an entire AMG URL, which is a lengthy string that includes the base URL, the album's name, and an album identifier:
http://www.allmusic.com/album/morning-phase-mw0002607867
However, the last part, the mw0002607867, is sufficient to generate a URL to the same page. By combining the base with the Album ID:
http://www.allmusic.com/album/ + mw0002607867
you get a simple, unique Album URL. As such, I've added the capability to save the Album ID portion alone. In addition, I'm also providing the Artist ID and the Track ID (so you can create Links to go directly to the Artist or Track page directly). The new fields that will be available are:
url => AMG Album URL
artistid => AMG Artist ID
artisturl => AMG Artist URL
tid => AMG Track ID
The existing fields will still be available:
rid => AMG Album ID
turl => AMG Track URL
However, and here's the Heads Up. The script will only read it's 'rid' value from the 'rid' field, which currently contains a full URL. And from now on, it will always store the shorter album ID into the 'rid' field and the full URL into the 'url' field. So if you want to save your full URLs, you'll need to create a new field and copy the URLs to that field. The script won't care if the value in the 'rid' field is a full URL or an ID - either will work.
Example: My 'rid' field is currently named AMG URL. Since the script will now store an ID into that field, and I want to keep the URLs (for the time being anyway), I'll create a new MC field called AMG ID. I'll copy the AMG URL values for all my files into AMG ID (using MC's Move/Copy fields tool). And I'll edit my amg-config.txt file to assign 'rid' to the field name AMG ID, and the new 'url' key will be assigned to AMG URL. New album IDs will be stored in 'rid' and the full url will be stored into the 'url' field.
Got it?
Side note: I've personally processed over 14k files.
Edit: I've now processed all my files. Today I added composer id/url to the script. With all these ID or URL fields available, you can create some nifty direct album, track, artist, and composer Links in MC to take you directly to the relevant page. I have, and am routinely using, MC Links for AMG Album, Track, Artist, and Composer data, which use the stored IDs, and if they don't exist, do a search on AMG.
