The video behemoth looks to compete with Spotify.

Billboard reports that YouTube is close to launching a subscription service with mobile listening in mind. The service will have both free and premium tiers, with the latter offering unlimited access to what’s available via parent-company Google’s All Access service. The premium service could also include the ability to listen to music offline and remove ads.

However, the free tier could also also unlimited access, as it appears that YouTube’s goal is the grow the user base for its mobile platform so that it can sell more ads. Billboard holds that having a paid tier would give YouTube more flexibility in packaging and selling music, possibly with an eye (no pun intended) to future synergy with Google Glass.

“We’re always working on new and better ways for people to enjoy YouTube content across all screens, and on giving partners more opportunities to reach their fans,” YouTube said in a statement. “However, we have nothing to announce at this time.”

YouTube is said to be working to release a product this year, joining a crowded streaming field that includes Spotify, Pandora, Apple’s iPod Radio, and Google Play Music All Access, among others. Additionally, it could come before Beats’ Daisy service and Neil Young’s Pono make it to market.
