Ok. By id tags I meant something like BEATPORTID = 234234
Something that can identify the file on the site so there would be no need to search by Artist + Title.
Got a screenshot of the Tag view?
Anyway I've added the script here:
/t/11341/1
Download the beatport zip file, extract it. You get a Cover &Preview#Single _ beatport.src file.
Copy it to this location.
Now check the Tag sources menu in Mp3tag for the new entry.
You can additionally download and start the Mp3tag Cover Preview tool. It will show you previews of the covers (unfortunately the beatport ones are very small)
You can also try the amazon or google scripts.
