I hate to cite Webster's again (please don't be offended

), but I must disagree with your characterization of music as 'intangible'.
1in·tan·gi·ble
adjective \(ˌ)in-ˈtan-jə-bəl\
: not made of physical substance : not able to be touched : not tangible
http://www.merriam-webster.com/dictionary/intangible Recorded music
is tangible, and tactile – CD, etc. Broadcast music is tangible – sound waves passing through air.
I've never seen anyone 'reproduce a house with a photocopier' either, but I have seen people robbed of their rightful compensation by unscrupulous people. Just ask any of the Black blues legends who never made a dime on their songs. Or, you could just ask Jimmy Page.
