I think Marty uses era appropriate source music ala Goodfellas and Badfinger was probably appropriate for the rhythm of that scene as it could on the radio in the background.

Vince put the song in the foreground having it act as the narrator to the scene. Consider the name of the song Baby Blue, which could be a street name for Walter's crystal. The opening line of the song: I got what I deserved, I don't think of it as a ripoff as a coincidence.
