Am I one of the few that strongly dislikes verbiage like 'Commercial use rights for songs made while subscribed' on their billing page, it feels and smells an awful lot like 'You'll own nothing and you'll be happy'. Also feels like another race to the bottom for yet another creative field. Not trying to dissuade usage of tools like this by others but it leaves a bad after taste.

Whilst it's not clear where the training data is coming from, how can I be sure that I won't accidentally trip up something like YouTube's Content Match tool or other companies whom act on behalf of a copyright holder? Or did I miss something?
