Apple filed for U.S. trademark applications in November for Beats 2, 3, 4, and 5, as spotted by French site Consomac. The applications use the same logo as Apple’s streaming radio station Beats 1. It’s previously been reported that Apple could create five more radio stations without having to negotiate new licensing terms. All signs certainly point to four new Apple Music stations at some point, perhaps in varied music genres or in different formats. While Beats 1’s Zane Lowe expressed some doubts about the longterm future of Beats 1, it seems as if Apple has very few concerns at this point. [via MacRumors]
