Now, when you listen to music streaming or subscription services like Spotify, Rhapsody or R-dio, your music picks will be factored into the Billboard charts. Previously, the charts only took traditional radio airplay and online song sales into account.
The change comes as more and more people flood low- or no cost music streaming sites. According to Nielsen, more than 625 million songs were streamed in the past week alone. That's an all-time high and far outpaces song sales.
So what does the iconic Top 100 chart look like with the new data? It might not look very different at all.
This week's chart is due out Thursday, and **spoiler alert** "We Are Young" by the band Fun will hold on to the top spot for a second week. Any changes that do happen may be slight as people tend to migrate toward the same music no matter where they get it.
"We Are Young" claims the first-ever number one title based on the new chart thanks to a boost from more than a million streams.
