This is what we've been talking about. The only thing to remember is that you get a share of the royalties - about 40%. Not all the record companies are represented but most modern songs are. What happens is that they create a Youtube page with your music on (there is a little 'provided by' notice) it does NOT go on your own YouTube account, just the one created for you. As they put so many tracks on YouTube, they have far more privileges than an individual has.
I'd not heard of these people, but I might try a sign up to see how it works and what they really charge. It looks like they get 10% of the royalties so that may mean there are no hidden extras. I note their restrictions are the usual ones - mash-ups and other medleys being impossible to negotiate automatically.
With all these things, make sure your name is unique. One of ours has got really messed up and an American artist of the same name has been merged with ours on Spotify, and although he is far more famous, his statements show he doesn't make huge amounts of money. We're using a different name for some of the people we represent now - their middle name included which makes it more 'unique'.
EDIT
This is the info you get when you sign up
- In consideration of the rights granted pursuant to this agreement, WATH shall pay to Artist a royalty equal to WATH’s "Per Video Income" multiplied by (i) forty percent (40%) with respect to Artist Videos embodying Compositions; (ii) eighty percent (80%) with respect to Artist Videos embodying Controlled Compositions; or (iii) twenty-five percent (25%) with respect to Lyric Videos (collectively, the "Royalty"). Per Video Income shall mean the actual income received by or credited to WATH in connection with and allocated to Artist Videos (or Lyric Videos) less any third party costs or deductions incurred by or charged to WATH including, without limitation, third party distribution fees, commissions and ad service costs.
- In the event that WATH receives a claim with respect to any Artist Video, then WATH shall have the right to withhold payment of Royalties in connection with such Artist Video or Lyric Video until such claim has been resolved.
That's a little different. I can't see what their definition of a 'controlled composition' is yet. If this is an opt in feature available to the original artist, then you're down to 20% and considering Spotify pay 0.002 cents per stream - that's a very, very small amount of money.
There is also the option to publish these to your own channel, but I'm not sure how that would work because YouTube would need to pay different organisations for different tracks - that would be somewhat difficult to track? probably a dedicated Youtube would work better. Imagine trying to validate random amounts of money like this?
