Popular radio host DJ Khaled is among those producing podcasts that will be part of Amazon's music service

Amazon on Wednesday added podcasts to its streaming music service, tapping into a trend and taking on rivals including Spotify and Apple.

Amazon Music added hit podcasts such as RadioLab and promised a line-up of original shows from radio host DJ Khaled, actor Will Smith and others.

The podcasts are included in Amazon's streaming service in the US, Britain, Germany and Japan.

"Our customers' listening habits are constantly evolving, and we know they're looking to us to provide them with a rich experience rooted in and entertainment," said Amazon Music vice president Steve Boom.

A follow up survey in the US found that 10 percent of younger listeners, ages 18 to 34, said they believe people should pay for podcasts and they should be ad-free, according to Statista.

"We're thrilled to offer customers a convenient podcast listening experience that fits their lifestyle," said Amazon Music podcasts director Kintan Brahmbhatt.
