There it is. Simple as day. Although, I would also accept, "stop putting music on your blog" and "get that Sh%tty music off your blog".
Yes, it is your blog, yes, it is nice to be able to customize the reading experience by adding an additional sensory input for the reader to 'enjoy'. And yes, not only am I able to not view a blog that I don't like (even though it is very good accept for the automatic music) - I will not read a blog with music that automatically loads. Simple.
Some of us enjoy customizing our reading experience by playing music on our PC (or mac) and having our own choice of music over powered by some stuff which - although very nice I'm sure- we would personally not listen to at gunpoint, and even then it depends on what kind of gun, is just darn anoying.
If you are going to have music on your blog, PLEASE, and I'm begging you here, make it optional. Make it so that the reader can click a button and enjoy what you love so much. I love that! I love sharing what you enjoy, I just want to be given the option of when to do it.
