I also highly doubt anyone who signed agreements to have their music included in the Free Music Archive would have been OK with this. The particular type of license was important to contributors and there's a difference between allowing for rebroadcast without paying royalties and allowing for derivative works... I don't really care to argue the point, but it's why there were so many different types of licenses for the original FMA. This just glosses over all that.
If you look at the repo where the model is actually hosted they specify
> All audio files are licensed under CC0, CC BY, or CC Sampling+.
These explicitly permit derivative works and commercial use.
> Attribution for all audio recordings used to train Stable Audio Open 1.0 can be found in this repository.
So it’s not being glossed over, and licenses are being abided by in good faith imo.
I wish they’d just added a sentence to their press release specifying this, though, since I agree it looks suspect if all you have to go by is that one line.
