Stream listening slipped about 2% month-over-month in May, according to the Triton Digital Webcast Metrics Top 20 Ranker. As always, RAIN views the information through the lens of 6am – midnight, Monday through Sunday. The key metric is Average Active Sessions (AAS), which measures the average number of simultaneous listeners.
Pandora, leader of the pack, dropped one percent from March, and stayed above 2-million average active sessions. Number two-ranked iHeartRadio slipped by 3%
Spotify, which had led the group for a year, left the Ranker service at the start of this year. Year-over-year comparisons are distorted by that exit. But if we remove Spotify’s numbers from the group total for May 2018, we see level streaming volume down 2% from May 2018.
Here are RAIN’s leader trendlines from Sep. 2009 through May of this year:
(We are leaving the Spotify line in place as an important part of the nearly 10-year RAIN/Webcast Metrics record.)
