My wife is a pilot and has put up some flying videos on Youtube with cover song sound tracks. She also puts music credits. Example: "Soundtrack by Lenny Krevitz, EMI. All rights reserved" in the copy. Then You tube puts up a link so people can buy that song via Amazon, iTunes, etc. Never had a problem.
