Fancy is already at Top 15 on US iTunes (with a 2nd version in the 100's) with only 30M Al and rising. Album release is coming next week and it's looking very promising for Iggy's breakout US hit.
Is Fancy the next Happy? Is Fancy the next summer smash hit?
I can honestly see it going #1, yes. Its sales are amazing when you consider how relatively low its exposure is as far as promotion, airplay and streaming.
