It could be 5 million people each hearing the song 20 times.Īud+ = Change in 'Aud' compared to the day before. It is cumulative, so '100 million' does not necessarily mean that 100 million people have heard it. Each spin is worth a certain audience value, depending on the station and the time of day. Negative 'Bullet', negative 'Bullet+' = Song is decreasing, even faster than before.Īud = Audience reached in millions. Negative 'Bullet', positive 'Bullet+' = Song is decreasing, but not as fast as before.

Positive 'Bullet', negative 'Bullet+' = Song is increasing, but it's slowing down. Positive 'Bullet', positive 'Bullet+' = Song is increasing, and more rapidly than before.

When the actual sales are reported by Billboard/Soundscan, I adjust the estimates one last time before archiving them, but they are not exact because they are still based on the iTunes popularity values. Earlier projections can be off by more, but they tend to be pretty good as well. The different artist pages are the main feature of this section.Ī: The final estimates at the end of the week usually aren't off by more than 10%. Q: The way you calculate the points is stupid, it's very important that you improve the methodology.Ī: The ranking should not be taken that seriously. Check the status page to see how long ago a country was updated. Important countries like the US are updated far more often than insignificant countries. Q: Why does your site always lag behind the true positions?Ī: The server is constantly downloading updated top 200s for all countries, but due to the number of countries it's impossible to keep the set up-to-date. I check periodically whether additional countries can be added. Some countries have a store that is so inactive that there's no top 200 to fetch. Q: Are all countries that have iTunes part of this?Ī: Almost. Due to the methodology it's fairer this way, although it does mean that songs with multiple versions are at a disadvantage.ĪRTISTS (GLOBAL ITUNES/SPOTIFY ARTIST RANKING) Q: Are all versions of a song or album included?Ī: No, only the highest charting version is taken into account. The points used for this chart have absolutely nothing to do with sales. If you want sales figures, use sources such as IFPI or Mediatraffic. If I were to use the actual market shares, then the US and the UK combined would dwarf all other countries. Q: Why aren't the points a sales estimation?Ī: The point of the chart is to measure the worldwide popularity of songs and albums. ITUNES WW (GLOBAL/EUROPEAN ITUNES CHARTS) Q: Why aren't there any popularity values for albums? Sometimes fake updates still make it through, so always use your own judgment.

You can tell the update is accepted as 'real' if there are no question marks in the header. My program reads the feed every couple minutes, and these current values are always displayed in the left-most column. Sometimes they go back in time a bit, or other weird stuff happens. Q: Why does your site glitch all the time? Why the incorrect updates?Ī: The popularity values from the iTunes feed fluctuate. Dark green songs show the strongest growth, dark red the weakest growth. For example, a value of 0.6782 means the song is selling 67.82% of what the #1 song is selling.Ī: When the popularity values update, the top 90 songs are ranked according to their growth, and then divided into five categories. Q: Why do you only serve static web pages?Ī: I definitely see the advantages of a more dynamic website, but this way it's not so easy to overload the server when there are huge spikes in traffic.Ī: They show how much each song is selling relative to the #1 song. You can also ask me for specific data sets if you can't find them on the site, or if they're archived here in an inconvenient way.

But feel free to use the data to make your own graphs. I'm also not a fan of graphs, I prefer to see the numbers. Q: Can't you do something about the layout? Maybe add some graphs? Make it mobile-friendly?Ī: I'm more of a programmer and data scientist than a web developer, so working on the appearance has never been a priority. I usually don't respond to business proposals though since I'm not interested. I'm mostly known for administering pop culture forum ATRL, and for being a huge fan of Italian singer Tiziano Ferro. I'm a guy from the Netherlands and this whole website is my personal playground.
