So I'm in a bit of a pickle. A long time ago, I began writing a story that I really only half-expected to finish. Now, over 100,000 words later, I'm rapidly nearing the end and would love to soon submit it to some publishers. Here's the problem. Back in my "just get the words down on paper" stage, I used the lyrics of a copyrighted song throughout a few chapters. I understand that this is a huge no-no, but now I'm faced with the prospect of going back and changing the song. I can't eliminate the music altogether, as it contributes to a major plot point; however, it does not by any means need to be THAT song. So as far as I can tell, my two options are: a) invent an original song/lyrics or b) simply use the name of a song that people would know well enough to hear as they read (eliminating the need to quote lyrics). Since the importance of the music mainly involves the melody, and since I am no songwriter, I'd rather go with the second option. What do you all think? If a song is popular/pervasive enough, is it feasible to just use the title and let the readers imagine the lyrics/melody in their own minds? (As a frame of reference, I'm not using a "pop" song. We're talking an old song that has been covered many, many times throughout the decades.) Hope this question makes sense. Thanks!
