Yes, I too sing loudly as I ride it started years ago when it only got the attention of the dogs who were going to chase me anyway, early in the mornings.  Now I ride mid morning and still sing aloud but usually they are praise and worship songs because I pray when on my bike and that is my God time, not reading His Word.  Giving Him praise and Thanks brings me peace, keeps me centered.  So yes, I’m all for it make a joyful noise.
