Retromania by Simon Reynolds.
Here we go again
. Covering everything from "mashups" to retreads of all kinds (reissuing older material , hauntology, reunions etc etc) this has a slightest air of grumpiness to it ... "Eeeh, twere all ferric chrome cassettes in MY day" etc. I agree with some of it, other parts equally educate and annoy just like all his books do tbh
