The launch of Apple's online radio station has already gone wrong

Apple launches its Apple Music streaming service on Tuesday, as well as its global Beats 1 radio station.

The iOS 8.4 update went live an hour before the radio station was meant to begin broadcasting, but it sounds as if something has gone wrong.

Everyone with the iOS update can listen in to Beats 1 now, and hear presenter Zane Lowe repeating "Test" and asking if his studio engineer can hear him.

Here's what you can hear right now if you tune into Beats 1:

"What about now? I'm ready when you are."
"You're getting us?"
"I'm hearing you through one way."
"Talk again please"
"Test."
"Anything, Jason? Test, test."
