Possible to retrieve long lost files?

I wonder if it’s possible to retrieve an old recording (two, to be exact) that I made with Audacity in 2007 or 2008. I uploaded it to Myspace and it was lost due to their server migration in 2016. I don’t have a backup anywhere and suppose my chances are minimal, but if there is any way I can get it back through Audacity, I’m all ears for instructions on how to go about it.

MySpace had deleted most of the old content by 2015. It’s highly unlikely that any of it still exists.
The “Way Back Machine” Internet Archive does not copy social media sites.
If it’s not on your computer and not on any backups that you have, then I don’t see how it could be possible to “retrieve” it.
