Don't know how popular this kind of thing would be, I think there was something similar done awhile back though.
I'm a big fan of the old dance music from the 80's and 90's. Was thinking maybe a show progressing through the 80's to 90's to 00's and now (soon to be 10's (I feel old now lol)). Could be pre recorded or Lost seems good at mixing all sorts of different things up in a single show. Should be fairly easy to progress though, the music did evolve without any major sudden changes.
Just an idea to throw into the mix, could be good to kick start the next era of 2010 and beyond.
