The man Justin Timberlake played in The Social Network believes that Spotify will be bigger than iTunes in a couple of years.
Speaking at a SXSW conference (quoted here), the Napster founder who has also invested nearly £10m in the streaming site declared that it had the capacity to overtake Apple's download service in popularity and clout.
"If Spotify continues growing at its current rate in terms of subscribers and users, we will overtake iTunes in terms of the amount of revenue we contribute to the music labels in under two years," he said.
This week, Billboard announced that it would now include Spotify streams in calculating rankings for its Hot 100 chart.
