Great post, unfortunately it got only few votes.
I can see your points why English so much means for you, specially as a musician.
"English is what Esperanto was supposed to be and that's a fact." Hard to digest as Esperanto speaker (one of the handful on steemit), but I came to realize it is true. In spite with English being so odd and difficult to grasp, people around the world put huge amount of money and afford in learning it. But it is not fair to use it as a common language because English speaking people got an advantage. It was one reason I learned Esperanto. Till now the problem of a truly International language is still not really solved. There are officially multiple languages recognized as such. I guess in future we will have more than one English. One, simplified and changed for international communication, then all the others, like Brish, American...for local use.
English is cool. Esperanto is interesting but somehow stiff.
One question, what is easier to learn for you guys English or French?
I used to know quite a bit of Esperanto but never used it so I forgot the most of it. I do agree we are still far away from a truly international language, I just think with English it's the closest we've ever got to having one.
And the answer to your question - I think equal effort is needed for both languages
