Hi, I wonder about this in general too.
And for a specific case, I consider making a collab with a classical opera aria by a classical composer.
Since it only would be a cover version of a Public Domain composition (of a long dead classical composer in this case), will there be no royalties/writer's fees at all?
The license fee is this case is $300, so I would hope there was some kind of royalty included, but it seems there isn't?
(Doesn't even state it, even if it would be an original composition of yours)
Thanks a lot in advance for sharing knowledge on this subject! (or for any reply too for that matter)

From the listing:
"ITALIAN-STYLE OPERA SONGS (ORIGINAL and/or PUBLIC DOMAIN) with Male or Female Vocals are needed for several $300, Non-Exclusive, Direct-to-Producer placements in a food-based documentary on PBS.
...
Broadcast Quality is needed (great sounding home recordings are fine).
