The nostalgia question greatly intrigues me.

Another area where nostalgia seems rampant is in entertainment. The music industry is a case in point. Growing up in the 1980s and 1990s, I noticed very little "nostalgia" for previous decades, although it crept in a little with some acts - Suede sounding like Bowie, Jamiroquai's 70s funk influences, that sort of thing. However, today it seems impossible to escape, and popular music is rife with it. The same is true in film and television, with endless sequels, reboots, rehashes, and flagrant nostalgic indulgences (not all of them are bad, I hasten to add).

The question is, what does this tell us about artistic innovation, and our collective state of mind?
