Billboard and Twitter have teamed up to present the "real-time charts" to track the most popular music being shared on the social network.
The first is Billboard Trending 140, which compares the frequency a song is shared over the past hour with the hourly average of shares in the last day. The second is Billboard Twitter Emerging Artists, which ranks songs from artists with less than 50,000 Twitter followers by the volume of shares in a 24-hour period. There will also be weekly summaries showing the most popular tracks on Twitter during that time span.
I wonder how that Aaron West & The Roaring Twenties song did virally.
