In any case, I think you are right about "Come In My Kitchen" - this probably needs to be taken down. Any others? you said "numerous clear violations"?
I don't have my blues song book in front of me. The basis for me saying "numerous" is that I was flipping through the book and finding songs that I might learn and then listening to them to see if it was something I might enjoy and/or be able to play. The back porch is a great resource for that. I found a few I thought were possibilities. That's when I created the SoundClick site and stumbled into the licensing canna worms. I looked up the ones I was thinking of doing and found copyright dates that indicated potential trouble.
I am thinking I will do some "Handy work" for now; St Louis Blues and Gulf Coast Blues are okay.
