I think you really can remove this Deezer from this xml file, .. their audio embedding is a joke, they only play the first 10 seconds of a song...
And this BooMP3 ... lol ... seems they don't have any audiofiles uploaded, very strange site ...
I mean, 160+ supported sites sounds great, but would be nice if the sites in this xml has been tested before, just to increase the quality and the usefulness of the xml
