"Shower" sounds a little like Rihanna's "Umbrella."
Buzzfeed has already pointed out the similarity, but go ahead and sing the words "under my umbrella" instead of "singing in the shower" in the hook. You'll see what we mean.
EDIT:Wait,it's true the hook is exactly like Umbrella's.Rihanna you better get you money.
Dr.Luke copying masterpieces as always.I don't blame him,Umbrella is perfect.
