Music stutters and stops playing

[Timo_West]

I'm using the destop app 1.0.1.1060 on a Macbook Pro with OSX 10.10.2

When I'm starting a song it plays for exactly one second and then stops. After a while it resumes but stops periodically while playing.

I'm listening in high-def.

It's not the internet connection. I have 39.66 kbit/s download.

Everything's fine when I'm using the iOS App in the same network.

Reinstalling the app and clearing the cache did not help.

What's going on???
