If you want to stream music for free on mobile devices, one of the best options currently available is YouTube Music (available on Android and on iOS). This app lets you browse and listen to YouTube as if it were a music streaming service, making it a formidable competitor to the likes of Spotify, Pandora, etc.

It gets even better if you subscribe to the YouTube Red program because Red membership unlocks a special feature: the ability to stream audio without video, which can save a ton on bandwidth and data usage. But what if you don't have a Red membership?

Fortunately, YouTube recently added a new feature that lets you only stream when you're connected to a Wi-Fi network. It's a common feature in streaming apps like this, so it's strange that it took this long to be implemented, but the good news is that it is here, so you should enable it ASAP.

All you have to do is open the side menu, select Settings, and tick the checkbox for the setting labeled Stream via Wi-Fi only. If you still want to stream on mobile data but only in non-HD quality, tick the checkbox for Limit mobile data usage instead.

The best part is that these options are available even if you're just a free user, but you should still consider getting a Red membership anyway. Despite some of the downsides to the Red program, you get a lot of neat benefits like ad-free browsing and access to YouTube's library of original shows and films.
