Here's something I've been attempting that you may want to try. Pick your favourite band for each decade, starting in the sixties. (Artists: i.e. Bob Dylan, Stevie Wonder, Michael Jackson - can be in a separate selection) this is groups only. (Which may make it easier)
My choices are:
1960s > The Kinks
1970s > Pink Floyd
1980s > Dire Straits
1990s > REM
2000s > The Killers
2010s > Mumford & Sons (though of course this decade hasn't quite ended yet).

One of the above favourites, yet to feature on the FRIDAY MUSIC SPOT is The Killers. So here they are: Live on Letterman with a cast of thousands… (I could have picked any number of their songs but this is one of my favourite favourites). 'A Dustland Fairytale'

The Killers are about to release a new album on 22nd September called 'Wonderful Wonderful' !
