Great article on Astronomy.com today.  The question is, would aliens even understand us if we communicated with them?

We take so many things for granted when it comes to communication.  For example, in Star Control: Origins, there tended to be an assumption that aliens would have a mouth.  Why would they have a mouth for communication? That seems to be a pretty big assumption.

It seems fair to ask whether anything that would encounter what we send out would be able to make sense of what we send out.

This might mean nothing. And the sounds the record produce might not even be in a frequency that something could hear.  The range of frequencies we can detect are pretty limited.
