41 = rank on the pop chart
+2 = change in rank from the day before
1031 = number of radio spins the song has received in the last 7 days
677 = weekly bullet - the increase in radio spins over the past 7 days compared to the same day a week ago (e.g., a song that had received 354 spins over the course of a week last Monday would have a bullet of +677 if it received 1031 spins in the past week)
9.269 = AI / Audience Impression - the audience the song has received in the last 7 days in millions
+156 spins = the amount of spins the song has received in comparison to the same day a week ago (e.g., a song that received 600 spins last Monday and 756 spins today would have see a spin increase of +156).
+78 bullet = the change the daily update had on the weekly bullet (e.g., a song that had a weekly bullet of 599 yesterday and saw a +78 change would have a weekly bullet of 677 today).
+0.764 = change in AI (e.g., a song that had 8.505 in weekly AI yesterday would have a weekly AI of 9.269 with this update from the gained audience from the additional spins).
Not sure how helpful this is, it kinda takes awhile to catch on. Not very intuitive.
