XBMC Music Library corrections

My XBMC installation is almost complete, but I have ongoing problems getting my Music Library to consistently work. I have the following issues/requirements: - instructions on how to create [login to view URL] in xml format, so my bootlegs and custom compilations display and play - research the possibility of having artist aliases point to the same artist in the database - instructions on how to create working [login to view URL] files in url form so artist can be found online and have proper information inserted into them - instructions on how to delete forum posts from the xbmc forum - instructions on how to remove 'various artists' from the artist library view - a solution for XBMC using a random thumbnail for unrecognized artists - a solution for my inability to update the music library on request - a solution for my inability to search for an artist manually - advise on what scraper will work best for artist and album information I will need to converse with you on Skype/Gtalk to demonstrate. Thanks for your consideration
