No I didn't, don't worry. I understand how it can be frustrating that the additional attributes do not support other product types. I actually don't know how the product_types work and didn't know they have a different page for collecting info. I'll take a look into it later. But if you look at ASA and the UPC/ISBN (ASA now replaces UPC in my next release coming soon...), you will see how to add fields. Perhaps you can let me know which files are used for music product types and I'll look into adding it in the next release.

That version of eBay Exporter requires the ASA attributes and there is not previous version that I can currently support. I'll take into consideration your requests and you can expect them in the next release.

I'm current;y beta testing my Amazon Exporter and I have ASA attributes ready to be released.
