According to industry sources, the song could sell 120,000-140,000 downloads in the week ending today (Feb. 1), its first seven-day period of availability. As for airplay, "FourFiveSeconds" will likely climb aboard Radio Songs, passing the audience sum that factored into its Hot 100 debut. Since no official video exists for the song, streaming, the Hot 100's other metric, likely won't yet contribute to the single's chart rank on any significant level.
But, adding projected sales and airplay, "FourFiveSeconds" should rise to … perhaps the Hot 100's top 25. Not anywhere near No. 1 – that looks like another battle between Mark Ronson's "Uptown Funk!," featuring Bruno Mars, and Ed Sheeran's "Thinking Out Loud," with the former likely notching a fifth week at the summit – but still incredibly impressive considering that the general public found out about the song's existence slightly more than a week ago today.
