I want to know the answer to the following question:
How many independent labels did the Merlin Network represent?
All the background I'm provided with is that "In May 2014, prior to the launch of YouTube's subscription-based Music Key service, the independent music trade organization Worldwide Independent Network alleged that YouTube was using non-negotiable contracts with independent labels that were "undervalued" in comparison to other streaming services, and that YouTube would block all music content from labels who do not reach a deal to be included on the paid service.". Is that enough to answer the question?
Answer: no
