For further clarity, I think all of those Lorenzo’s Music tracks are actually CC BY-SA. for example, http://freemusicarchive.org/music/Lorenzos_Music/Picture_it_all

Mike is just using the default blocSonic license (which I had him change from BY-NC-ND...not perfect, but progress) and Lorenzo’s Music has given blocSonic authority to release remixes under a different license.
