Quoted from TrevixClemson:
I'm 32 and would take Buffett over Iron Maiden any day of the week.
Also, as a side note, apart from all the other stuff he has going, there is also a new Broadway show called "Escape from Margarita ville" that is very popular. I think that alone shows JB is still very relevant. He came out at end of the show I went to and was selling signed posters with the cast to raise funds for Hurricane Harvey relief...
No reason not to have both. I am a fan of both bands.
