5. Rage Against the Machine
Rage Against the Machine had a pretty nasty breakup in 2000 but, seven years later, they reformed as a 1990s nostalgia machine. They played festivals all over the world without writing a single new note of music, grossing millions upon millions. They haven't toured since 2010 and they haven't done a single show since a once-off Los Angeles festival date in the summer of 2011. There's been no official announcement of another breakup, but it sure seems like they are once again out to pasture. Give them a few years, though. There's life in that band yet.
