I do not get the success of "3" at all.
I enjoyed quite a bit of Blackout, but this just sounds like the first draft of a Lonely Island short starring Jane Krakowski. “We’ll throw some jokes in the verse later, just sing ‘are you in?’ over and over for now.”
(Ok, “1, 2, 3/Peter, Paul & Mary” is a great hook - Samberg would be proud - but I’m still amazed what people will part with 99 cents for.)
