New, possibly stupid question

[Bauran]

Let me preface by saying I rarely, if ever drive without my music blaring do this issue (or non-issue) could just be a quirk of the car, I don’t know. Anyway, I was in a drive though yesterday and noticed an inordinate amount of racket coming from beneath the car as I had put it in neutral and since the teller was taking too long I released the clutch and put on the emergency break.

Now, the question, with the clutch petal depressed, no noise, as soon as I release just to sit idle I get what I can only describe as a clatter. Depress the clutch, nothing...and so on and so forth. Now I'm fully aware that in tight quarters such as a drive through that ANY noise is exagerated to the point of concern but this one seemed at the very lease irregular.

Paranoid or something I need to check in on?
