I think it just goes to show that our tastes (in both literature and music) are quite eclectic. I have over 300 novels, hardback and paperback, in carrier bags and boxes in the back room. They range from Harold Robins' novels, through various crime thriller writers such as Childs, Paterson, Rankin, etc, the ubiquitous Grisham novels and almost everything Stephen King has written. There are also many autobigraphies (maybe one or two biographies) and the hilarious 'The Queen And I' by Sue Townsend, the only 'comedy'novel i possess, though, on Kindle, i have read the entire Barney Thompson series by Douglas Lindsay - ridiculously funny. I also have a medium sized bookcase housing many reference books, books of famous quotations, books on specialist subjects, etc.
As for my music; Sabbath, Floyd, Zep, Lizzy, Queen, Purple, Yes, Early Genesis, Grateful Dead, Supertramp, Yazoo, Erasure, Eurythmics, Kate Bush, Florence And The Machine, Dire Straits, Mumford & Sons, Kings of Leon, Cohen. Dylan, Clannad, Black Star Riders. As i said, quite eclectic:-)
I suppose what it really tells us is that, as our moods change, so do our tastes at that particular moment in time.
