Music for Prime Time: A History of American Television Themes and Scoring, written by Jon Burlingame, is a detailed account of the use of music in television, primarily theme songs but also touching on music within some shows. I listened to the audiobook, narrated by Paul Woodson, and found it to be very good.
While theme music hasn't gotten a lot of attention in academic circles, it is overstatement to say it has been ignored. Both when I was a student and when I was teaching, theme music was referenced when it impacted what we were looking at. What I don't recall is attention being paid to it exclusively, always in relation to other elements of the show.
Since I am no longer in academia, I come to this book more as a casual reader rather than a researcher. I think for this kind of reading the audiobook might be the best option. There is a lot of detail here, and listening to it allowed me to catch the bigger picture without the tendency to skim the parts that, while essential, serve a closer reading rather than a broader more nostalgic reading. That said, if I were still teaching and doing research I would want the print version, it is an excellent reference book as well as a narrative history.
I found the early history, the ways in which names had to be changed or hidden, credit wasn't given, and stock music for emotions (suspense, scary, ominous, slapstick, etc) was composed en masse, to be very interesting. I wasn't aware of the union issues and the libraries that kept composers from collecting royalties. Fascinating stuff.
For a casual or popular reader, I think the nostalgic aspect will play into how much you enjoy the book. There will be a lot of times you'll start humming a theme. You may even end up doing what I did, find some of the music online. This was both for music I was humming already as well as the music I couldn't quite recall. This made the book that much more fun.
I recommend the audiobook for readers who want to get the history and the nostalgia but aren't likely to need all of the details. For those who want or need those details, I think the print version will suit your needs better. Either way, the work itself is recommended for everyone with an interest, from those who remember their TV viewing youth to academics.
