Lyrics are intellectual property, like text and images. If you use someone’s property without permission, whether it’s a car, a bicycle, or the words to a popular tune, you are violating their property rights.
Using lyrics is particularly risky, not because they are special in the eyes of the law, but because they are owned by music companies that aggressively protect their rights. You could get a lawyer letter demanding you “cease and desist” using the lyrics. Translation–shred every copy of your book, even though the infringing words are 25 out of 95,000. Worse, you could be liable for monetary damages.
