Turn up the volume, then tweet.
New Billboard Twitter Real-Time Charts launched today use social media chatter to rank popular songs.
The "Trending 140" is a constantly updated list of the most talked about and shared songs. The list includes links to play the songs, which move up and down the chart based on social media buzz. A 24-hour snapshot of the chart is also available.
The "Emerging Artists" chart measures songs by up-and-coming singers based on how many times songs are shared over 24 hours.
So what counts as a "share" for the purpose of moving a song up the charts?
Twitter said, "Each real-time chart will provide a snapshot of the top U.S. hits as well as emerging tracks and artists who are moments away from being discovered."
Austin Mahone's song "Shadow" was the first to top the Trending 140 chart.
Both charts will also be summarized weekly for Billboard.com and Billboard magazine.
