For any given LFSR length, there are one, or more, or a lot more, choices for feedback taps for a maximum length sequence.
For a reasonable random generator you want to choose a set of taps that are distributed along the length, with one pretty close up front.
The setup you have there with two taps at the end effectively creates a transmission line, and that's what you're hearing.
