How do I find my distributor.

[jramawitaj]

Is there a way to find what distributor uploaded music to my account. I have already contacted a few services I thought may have it but the search is stil empty. I have older music on my account that I wish ot have removed but I am not aware of the distributor that was used during the initial upload a few years ago. Is there a way to find out what company or entity uploaded it? 

And if they are not around any more is there a way to get content removed or changed without them?
