Thanks, Michael!
The couple of libraries that I tried to browse were Crucial Music and Jingle Punks with no avail. If they have a library that you can browse, they don’t make it obvious. Either that’s the case, or I’m just not seeing it for some reason. But thanks for the links to the libraries that you cited. I’ll go and check them out.
What about my question on registering to ASCAP as a publisher as well as a writer? Any thoughts?
