I have a book written and I include at the beginning of each chapter the lyrics of a meaningful, somewhat or overtly relevant song. Prior to actually publishing, I plan to solicit "courtesy permission" from the one (usually a recording company) who owns the copyright. My experiences from contacting anyone of any greatness is the responses are fewer than the frogs and crickets in the woods. I have another legal method. This time, if I send an email or letter, I'll do something the same as what happened to me once when I sued a company for payment on an expensive sign I made for them. The company I did the work for sent me a check for a fraction of the amount do and put the words on the back of the check and in their accompanying letter that if I cash the check, I am releasing them from any further obligation to pay. That held up in court. I lost my case. Another aspect of law is "The Tacit Agreement." If I say I'll mow your lawn for $20 and you say nothing, I may mow your lawn. As long as you did nothing to stop me, you owe me the money because you made a tacit agreement with me. It is possible to apply this to getting courtesy permission. If I send out an email that gives a reasonable time frame to respond with a decline or it is tacitly granted, in such words that are not threatening, instead relieving the owner of the need to respond at all, that should be enough. If they respond to decline, I don't use it. If they respond to agree, I do. If they do nothing, I use it. Logically, there are so many lyric sites out there that are making money off Fred Zeppelin et al, that it's nearly a given that if I'm not pasting a bootleg CD onto the page, I should be okay. Ethics says I should ask. If they decline I can always write a Weird Al Yankovich type of parody to replace it with. For instance: Grandma hit some people who were walkin', Those poor people never had a chance. Last time all they did was take her license, This time that ol' judge will make her dance. All she did was go out on a beer run. Gramps and me just waiting in suspense. Guess we should have went out to the state fair, And hung out in one of those ol' beer tents. Well... what's the worst that can happen?
