I appreciate your work and how you are publishing under cc. Myself, I am a bit more restrictive, and I usually don't openly advertise it, but my images on Flickr are marked:
Usually when peeps ask if they can use something for commercial purposes, such as a album cover or magazine, I let them use it free (if I like the concept) - but I like to be asked. On occasion I had asked for a copy, like for example a magazine or a CD.
Otherwise, for their personal use only, like printing a poster for their dorm, go ahead. And if it is non commercial (websites, videos, blogs etc), then attribution is all that is required.
Myself, I appreciate the work other artists create - and had used cc music (with attribution) on my videos.
Quite a few videos of mine use music from Kevin MacLeod: http://freemusicarchive.org/music/Kevin_MacLeod/
Here is another link: https://creativecommons.org/about/program-areas/arts-culture/arts-culture-resources/legalmusicforvideos/
I began because I wanted to give something away to support the free federated networks. I also had no illusion about people respecting art on the internet, so just making it legit in the first place seemed an interesting experiment. Then I started earning a little bit of money from my art in this way, and of course have been thinking about how I can earn more... But in the end it seems we think pretty much the same about things. I am never going to be a commercial artist (my wallet tells me that) and maybe it will never get to a point where it matters anyway :)
Thanks for the MacLeod link i am listening now.
