But the company’s plans for the Beats Music brand are unclear. One possibility suggested by Wall Street experts and industry analysts was that the name would eventually be retired and streaming music would be incorporated into iTunes, with the Beats brand preserved for headphones and other audio products.

When Apple announced the Beats deal in May, its executives were vague about what place the Beats service would have within the streamlined Apple ecosystem, but said that it would coexist alongside iTunes. Jettisoning the Beats Music brand and incorporating its streaming service into the iTunes platform, if it happened, would represent a change in Apple’s thinking.

By absorbing Beats, Apple could gain the kind of simplicity that it craves in its evolving plans for digital music, with a single consumer brand — iTunes — representing its music offerings. While subscription services are still a relatively small part of music sales, accounting for just over $1 billion of the $15 billion global music business, they are growing rapidly. But download sales, which Apple has dominated for a decade through its iTunes store, are beginning to decline quickly.

Beats Music, which introduced its service in January, has not announced its user numbers but has been estimated to have around 250,000 paying subscribers. Spotify, the leading subscription service, has 10 million paying users and another 30 million who use a free, ad-supported version.

Ending the Beats brand would be consistent with how Apple has handled acquisitions in the past. Last year, for example, it bought the start-ups Embark and HopStop, which provided public transit directions, and put their employees to work on Apple’s Maps service. And after Apple bought the music service Lala in 2009, it shut the service down and incorporated its workers into iTunes.
