Wait, you mean all those bands and song names are real? I thought they were all made up.
Gee, I think we can guess who's not exactly au fait with the contemporary music scene....
The only made-up ones are the ones who perform live. And most of them are somewhat obscure, being punk bands and not stuff you'd hear on the radio. But yeah...real bands, real songs.
BTW:
I asked my law teacher about this a while ago, she said that even quoting a part of lyrics is fine, because it goes under some 'quotation' privileges... She used a smarter word, but I only remembered her point, sorry
I wonder if your law teacher was talking about the Fair Use Doctrine? Either way, it's very odd advice for a law teacher to give (are you sure she knew you were referring to quoting lyrics in a novel for sale, an not, say, in a term paper?), because there's a good chance that quoting even part of a lyric is not in fact fine. Because Fair Use requires that the usage be a small/"not substantial" portion of the quoted work (along with other restrictions), and because most songs are not very long...quoting songs can get you into trouble, legally and/or financially, in a novel you're trying to sell. And technically only a court can decide whether or not the quote in question falls under Fair Use, so even if your usage does, you can still end up paying out quite a bit of money in legal fees.
I have a friend who has to give up a portion of every dollar she makes on a particular book because the writer of the song in question saw his/her lyrics quoted without permission and decided that wasn't on. She has to do all the calculations and paperwork, too.
It's not a situation you want to get into.
