Music for adverts is not notable and has the air of the promotional, the fact that he has released two CDs will bring in more reliable sources. Perhaps a seperate section on the company itself can be recreated if there are enough sources to make it notable. 
 * The bullet-pointed history section contains too much trivial information. An unspecified appearance on a live DVD or being a guest on a TV show does not add anything encyclopaedic. Did he perform? Or score? Is there anything of note that involved his contribution? That is unclear.  
 * Due to the ambigious headings there is an overlap on the documentary material. That needs to be listed in the music career section only. 
 * The collaborations section reads like a list and does not indicate notability and what those collabortations were. That needs to be detailed. 
 * There are reference errors throughout - external links should not be used and acceess and source dates are missing. 
 The aim of the edit as implemented was to improve the structure, apply the required WP:MOS to ensure encyclopedic standard.
