I agree about the Beethoven. It is used by others also. I think it is a crime against humanity. I guess when it is in the public domain we are going to get this from time to time.
Beethoven's prototype for the 9th symphony the Choral Fantasy, has the solo piano passage that Dean Witter used for a long time. Everytime I hear the Choral Fantasy now, my mind waits for that voice to come on. !#&%!!
For copywrited music I find it interesting that David Byrne (Talking Heads), who became famous by making fun of the establishment with his music; sold the right to use his song "Like Humans Do" to Microsoft. It is the music featured with the Windows XP operating system, in commericals and what you hear when you turn your computer on for the first time.
