I have a couple of open submissions of recordings by Izzy Cox.
The Harlan Howard song Busted - https://secondhandsongs.com/submission/108976
And Hank Williams I'm so Lonesome I could cry - https://secondhandsongs.com/submission/121244
Both clearly covers and the Hank Williams song is announced as such.
But both are registered as original copyrights by Isabelle Cox with ISWC - T-913.414.728-7 and T-913.414.734-5.
So, arguably and legally, they are not covers but originals.
My head aches.
