Best cloud manager

[JRCT]

I have a gmail account with some free Drive storage.

My wife has Hotmail and OneDrive.

I keep all my uploaded CDs and downloaded music in Googleplay.

Most of my photos are in Flickr.

I now have an iMac and there's a cloud option with that too.

What's the best way to amalgamate all of these so I can search in one place whilst taking advantage of the free storage capacity that each one of these offers?

Someone's wisely pointed out is that you could point dropbox, google drive, microsoft onedrive etc all to one folder so that they sync. It means you also get more backup copies for free...
Failing that, I guess you'd need to set some more complex rules as to what goes where - i.e pics to flickr, docs to icloud et etc,
