One Hit Wonders: Robin Thicke, Icona Pop, Daft Punk, Capital Cities, Anna Kendrick, Bauuer
Two Hit Wonders: Imagine Dragons, Macklemore(even though I hope not), Pharrell
Robin Thicke had a hit in 2007, so he won't be one. But he'll be a one hit wonder in the UK.
Get Lucky is Daft Punk's only Top 40 hit, so them along with Bauer, Anna Kendrick, Lorde, Of Monsters and Men, Capital Cities and sadly Icona Pop and Krewella
