recommend mp3 player?

Hi,
My blog site is going to be for my band, and I want to run an mp3 player on it. I’m lost about how to approach it. I would like to run it in the sidebar or at the top of the screen in the header. I don’t want it to play right away, people should have the option of clicking on it. I don’t want the music to be interrupted as people scroll through pages and posts.

Is there a good wordpress plug-in for this? I haven’t found one yet. Is there some sort of off site player somewhere I could link to? Or maybe a player that launches in a pop-up?
