Since Beats launched its Beats Music streaming music service earlier this week, the launch has been plagued by reliability issues and new customers not being able to sign up.

Responding to these complaints, Beats CEO Ian Rogers has sent out an email to customers with an explanation:

Notably, for people who register this week, free trials will be extended by seven days. That is essentially the trial being doubled as the free trial was initially seven days.

Due to the extremely high volume of interest in our service some users are experiencing issues. Most people are unaffected but our priority is to give everyone a great experience. We prepared for issues like these, have a plan, and are going to hold off on letting more people in while we put this plan in action.

For those of you that claimed your name in the lead up to launch, we still have your username reserved and we’ll be in touch with your invite. We appreciate your support.

Everyone who registers this week will get an additional seven days added to their trial.

We’re staying focused on bringing you the best music experience from the people who know what song comes next. Stay tuned, and thanks for being excited about Beats Music.
