loop: "true" = automatic playback
You can this not deactivate.

Alternative:

HTML5-Player in a HTML/Widget:

(<audio controls preload="auto" autobuffer>)
(<source src="music/20_Flight-Rock-(live).mp3" />)
(<source src="<span>music/</span></span></i></span><i><span><span class="ff2 cf5 fs20">20_Flight-Rock-(live).ogg" />)
(<source src="<span>music/</span><span><span class="ff2 cf5 fs20">20_Flight-Rock-(live).wav" />)
(<p>Your Browser is not compatible with this HTML5 Audio.<p />)
(</audio>)

(Code is here not correct, does not go here, see my link)

Do not use spaces in the files.

HTML5 player is browser standard, you need 3 types of files for all Browser.
