The OVA was released 2 years after the single, and the single doesn't mention the OVA (of course, since it didn't exist yet), so in this case the product shouldn't be added.
I don't think it should be written in the notes either as it would be a mess if every single/album got edited every time a song gets reused in something which didn't even exist when the album came out.
