When the shout2send plugin receives tags, it was previously appending the new tags to a taglist, as such the tags were not getting updated properly. 

Additionally, while parsing the tags, the artist and title were getting prepended and appended to a string which composed the "song name" for that stream. As a result, the artist / title were getting repeated over and over.

Both of these issues have been fixed in the patches provided.
