Move over, Taylor Swift. Spotify is winning, at least in Europe.

In the first quarter of 2014, revenue from Spotify streams in Europe were 13 percent higher on average than revenue from Apple's iTunes store for artists working with Kobalt Music Group, Kobalt announced on Wednesday.

"This has not happened in the United States yet," Kobalt CEO Willard Ahdritz said in a statement to CNBC.

Founded in 2000, Kobalt is a leading independent music publisher and helps thousands of top artists, songwriters and publishers (including Paul McCartney and Dr. Luke) collect revenue from online streaming services.

The crossover between platforms has been rapid. In the third quarter of 2013, revenue from iTunes in Europe was 32 percent higher than that of Spotify, Kobalt said in a release. That lead narrowed to just 8 percent in the last quarter of 2013.
