It's now or never for companies looking to establish a foothold in the rapidly expanding music-streaming industry.

At this point, there are two front-runners, Spotify and Apple Music, and assorted small fish, including TIDAL, Google Play, and Soundcloud Go. The Wall Street Journal reports that Pandora will join the scrum when they launch a music-streaming service of their own as soon as September.

Pandora already has an active user base of 100 million. According to the company's CEO Tim Westergren, the company will offer a free tier, a $10 monthly plan, and a third, more affordable option with "mid-level" features. As of now, Pandora offers a ad-free listening for $5 per month as well as a 99-cent day pass.

Stay tuned for more information regarding Pandora's impending streaming service.
