rip some of the Shoutcast downloading code out of the no longer included playlistbrowseritem.cpp file and use it to do a quick and dirty testing hack in the ShoutcastService to be able to showthe genres. This MIGHT actually work, only, as many of my projects at the moment, it stalls because KIO cannot complete a file download but always stalls after a few percent. Also, this is code just for testing, it is to be considdered extremely harmfull to the general well being of any descent programmer. Approach with extreme caution
