Explanation on chart's concept (Spotify, Kworb, Radio)

[Star 4,409]

First of all, Let me start off by thanking to most of the members in Chart thread for helping out with compiling some stuff that I really need the most for making this thread. Secondly, this thread will be hopefully pinned by Mods in explaining the charts term that has been posted in the chart thread. Instead of making the post asking for explanation, I suggest you to check out everything in here. 

KWORB
This is based on iTunes position of the song, which can be considered as "sales" of the song.

Simply, it is showing the song's position depending on the schedule, especially mentioned in the 3rd column stating that it was last updated in 2 hours ago.

There will be 5 different colors, or bars, if you say.

Dark Green represent heavy increase of the buying of the song compared to the earlier time (4.5), Light Green representing a lighter version, White stating the neutral, or you may say "Stability", Light Red means it is decreasing as not many people are buying it compared to the earlier time (4.5), Dark Red means it is losing more than earlier.

If you see the second song, i.e. Ed Sheeran - Galeway Girl, having 0.5109 points meaning that it is selling almost half of what #1 song is selling. Simply think that #1 song is selling 10,000 copies, the second song, having 0.5109 points, is selling 5,019 copies. 

Lastly, Whenever you see "???" in 3rd column, it means that it is glitching most of the time. Rarely, there is a time where it can represent the actual point which can be identified easily if you see no difference in the previous column along with the current column that is under "???" meaning that it is a glitch, but if the number changed, then it can be a real update! [Thanks to @Cortex for this]

RADIO

Radio plays an important role for the airplay which contribute to the overall success of the Billboard Hot 100. So, in short, it is "airplay" of the song. To check for the radio update on the song, you will need an access to mediabase, a site where radio updates and statuses are collected and posted, luckily there are some members here who have an access to that and posted it in here, regularly. Please thanks to these [*members name]

Here you can see the airplay of the song of the day:

50     49      LADY GAGA    The Cure    2720    1402    1318    14.818
+116 spins 
-27 bullet
+0.236 audience

The format is:

LW TW Artist Song Total Spin Spin+ Aud

+xxx Spins

-xx bullet

+x.xxx AI

LW: Last Week position of the song

TW: This Week position of the song

Spin: Total Spin means total number that radio has been spinning the song. Supposedly, KIIS has been playing TC 10 times, it will be counted as "+10 spins". 

Bullet: It represent an increase or decrease of the spin from the last week to the current week. 

AI/Aud: Represents "Audience Impressions" and is denoted in Millions. Here, "+1.234M" representing that 1.234 Millions audience heard the song that was playing on the radio.

Now, on to the MOST IMPORTANT part of the Radio's term, ROLLING EFFECT. It always start after 7 days of the first spins played on the song meaning that after 7 days, it will start to adjust. According to the figure below, Say the first day, The AI is +2.212M which is normal and healthy. On the 8th day (that is when rolling effects start), it will have +0.100M which means that it actually had +2.312M update. But because of the rolling effect and adjustment, it will get only (+2.312 - 2.213M) = +0.100M

Let's take this as an example

First Day: +234 spins/ +234 bullets/ +2.212M AI

Eighth Day: +10/-224/+0.100AIM

Fifteenth Day: +100/+124/+1.234M

Twenty-Second Day: -12/-146/-1.125M

Twenty-Ninth Day: -123/-269/-2.235M

Here, you can see that the 1st day has amazing positive spins, bullets and AI. In the eight day, you will notice the change in everything, it does not means that the song is peaking until you see the change in the next week (Remind you that rolling effects does not start after consecutive per week after the 7th day, it starts continuously after 7th day). If you see positive in spins on 15th Day, then it is healthy and moving on and is certainly not peaking.
On 22nd day, you will realized that it is getting small negative bump which is fine. But if the spins does not turn into positive on the 29th Day, it means that the song is peaking and starting to fall.

Rolling effect is done to ensure that the song get peaked easily because without rolling effect, we would have trillions AI update which does not make sense.

SPOTIFY

Spotify plays an important role when it comes to streaming. Apple Music, Spotify and Pandora are the main market when it comes to streaming. 

TTH is a popular playlist titled "Today's Top Hit" in which most potential song are being listed. It can be either Payola or Popularity measurement.

"To check for the radio update on the song, you will need an access to mediabase, a site where it collects and posts the radio updates and statuses..."

It should be "which collects and posts..." or "where radio updates and statuses are collected and posted."

Thank you for this! Definitely helped.

So has The Cure peaked?

[JiU 2,194]

What about youtube data? Doesn't that affect the charts as well?
