Just-spotted trademark applications from Apple-owned Beats Electronics, LLC point to Apple’s plans to introduce more live streaming radio stations to its Apple Music service to accompany its 24-hour station, Beats 1. It appears Apple’s radio lineup may be expanding to include Beats 2, Beats 3, Beats 4, and Beats 5, according to the applications filed with the U.S. Patent and Trademark Office in November, Techcrunch reports.

The applications were first reported by French blog Consomac, then picked up by Appleinsider, which noted that there are applications for both the names of the stations themselves, as well as the logos, which include a stylized letter “b” followed by the station number.

The news is not all that surprising to those who have been following the developments with Apple Music in recent months, as a report from The Verge in August indicated that Beats 1 may not be Apple’s only official station for very long. According to its sources, as part of Apple’s deal with labels for Apple Music, the Cupertino-based company had negotiated licenses for up to five additional stations to launch following Beats 1, without requiring amendments to its deals with the labels.
