The YouTube app for Android reportedly consists of a code that hints towards a possible 'Music Pass' service, in tune with the video site's plans to launch a subscription music service.
The Google-owned site recently announced its plans to launch a subscription music service of its own and the code with the Android app can help YouTube achieve just that.
According to The Verge, a Music Pass service would offer unlimited streaming, offline syncing, background playback, and no ads on millions of songs.
The code could also lend support for offline video watching including references to offline versions expiring, similar to a movie rental service.
The report said that such features already exist on Google 's Play Movies and TV shows, but incorporating it with the video site giant for a fee would help the search giant gain more revenue.
