Yep at this time Musiconomi is just another "make us rich" white paper. Whereas Musicion is real service, community and ecosystem with its on currency and economy that is already gaining traction.
We heard more and more ICOs around music these days(at least 4 of them suddenly emerged). Whether on MUSICOIN blockchain or not is not important, the most important thing is whether the team really understands music industry, understand the problems and really serve all stakeholders. A whitepaper definitely can't prove anything, leave alone credibility issues.
