Anyone able to tell me what the figures actually mean? It looks like gibberish to me, but I'm sure I'd grasp it if someone told me.
An audience impression is a measure of how large an audience a song reaches, and is usually expressed in millions of people. For example, one play by a New York radio station might be rated as a certain number of million impressions, meaning that this is a reasonable if necessarily inexact estimate of the number of people who heard it.
A measure of how many people who heard the song á day.
CARRIE UNDERWOOD - Mama's Song: 25.659 (+ 0.507)
Which means about one half of million people heard the song that particular day.
FLORENCE + THE MACHINE - Dog Days Are Over: 3.687 (- 0.049)
And in this case, I think the "-" stands for "less" audience than before.
The temporary airplay points: 23.659 in Carrie Underwoods case will be added with the digital numbers of the same week, which then together decide where on the Billboard Chart it will end up.
I hope I explained it correct and that first part is from wikipedia.
