I am very happy you liked my music and thank you if you will buy the EP!

I checked your links and I am following you here on Steemit, very cool illustration and artworks, and checked your website too.

About CC license, you are right, we can not only live by promotion, but this license doesn't prevent from selling one's works.

For example, having a free for non-commercial use artwork doesn't mean you can not accept money for its commercial use (or for a higher quality version).

If you are a visual artist, you may have a CC license on the digital copy but still charge money for the physical one, etc

Still the problem of being an artist and not receiving the right economical reward is a very old and common problem (in the past centuries also very important artists had it): now we have some new opportunities with social media and crowdfounding, but still is not easy!

Thanks again for your kind words and support :)
