I love music. And in fact I've had music on my blog. BUT I did not set it to auto play.
I put a note on the sidebar and gave my blog visitors the option of listening.
What gets me--my rant--is the blogs that have the player set to auto, and it's waaaaaay down the page..you have to search for it all the while it's blaring away.
Folks...if you're going to have it set to auto play, at least have it at the top of the page where it can be easily discovered and muted need be.
