Apple has been trying to get its new iRadio—a streaming music service—ready for the summer, however the company has run into a bit of a hiccup. Apple and one of its partners in the operation, Sony, are in disagreement on how to deal with when a customer skips songs, according to CNET.

According to sources familiar with the negotiations, the two parties are currently in disagreement over how much Apple should pay when an iRadio user decides to listen to half of a song, and then skip it.

The new radio service most closely resembles the popular online radio Pandora, and comes with some new features. For example, in addition to the skip feature, if you are listening to a song and decide you really enjoyed a certain part, you may rewind the song.

Sources say a week ago Apple reached a deal with Universal Music and is close to hammering out a deal with Warner Music group.

The Apple and Sony skipping disagreement does not simply effect the two parties involved. Higher-ups at other music labels are growing annoyed with the issue because they see Apple’s music service as a huge plus for the music industry.

Streaming music is the segment of the recording music industry that is growing at the greatest speed. The fact that Apple is offering such a service to iPhone users and linking it to iTunes could allow the industry to grow much faster.

Sony declined comment and a spokesperson from Apple was not immediately available for comment.
