I like Lorde, Pink, Adele, Alicia Keys, John Legend, Lady Gaga, Coldplay. The song "Rude" I like, not sure about the band Magic or any of their other songs though. I think Of Monsters & Men might count as popular, so them. Foo Fighters may count as popular?
I like Sia, she's interesting, but don't really like the songs, though I don't mind them.
