As Apple played up the release of its music streaming service at WWDC, many investors and consumers may have overlooked one important announcement, analyst Gene Munster said Tuesday.

"This idea of being able to do [native apps] on the Apple Watch … is going to create some new features for the Watch which [are] desperately needed," Piper Jaffray's senior research analyst said in a CNBC "Squawk Box" interview.

Developers will be able to create these native apps by using the watchOS 2, Apple Watch's new operating system. A beta version of the system is currently available for developers, while the full version will be arriving this fall.

The tech giant made a series of announcements Monday at its Worldwide Developers Conference in San Francisco, including the unveiling of the much-anticipated music streaming service Apple Music.

Still, Munster said he was not overly impressed with the service. "They played up the music service a lot, but very few people are going to use that," he said. "Spotify has about 15 million users, and there are about 400 million active iPhones out there ... The numbers are so big in terms of the phones, I guess it kind of skews my perspective of lots of people using it."

The service will be available for iPhone and Mac users on June 30 and will cost $9.99 per month or $14.99 for up to six family members, said Eddy Cue, senior vice president of Internet software at Apple.
