I want to know the answer to the following question:
Along with Mumford & Sons, Of Monsters & Men, Ed Sheeran and The Lumineers, what indie artist has had adult contemporary success?
All the background I'm provided with is that "In the early 2010s, indie musicians like Imagine Dragons, Mumford & Sons, Of Monsters & Men, The Lumineers and Ed Sheeran also had indie songs that crossed over to the adult contemporary charts.". Is that enough to answer the question?
