So...eventually some more digging brought me to mailboat records. I would assume I would e-mail them regarding Buffet? The only e-mail they had that I found was firstname.lastname@example.org, so I'm gonna try that tonight.
As for Springsteen, I clicked the Columbia records link, and after some digging around, found the link that says "Send Feedback". Hopefully I'm doing it right, at least I'll find out soon enough tonight.
So, my lesson to all who are looking to contact their favourite artists:
Don't trust websites. Google that s***.
