FireTube is an app that lets you play YouTube videos in the background. Thanks to this feature, you can use the app as a music player and take advantage of the millions of songs you can find on YouTube, even with your device's screen turned off.
Using FireTube is really simple. Just tap on a video for it to start playing automatically in the music mode. Instead of watching the video, as with other apps, you'll see a still image while you listen to the audio. This way, the app consumes much less data from your plan.
Once the audio starts playing you can close the app or turn off the screen. Don't worry, the sound keeps playing without any problems. You can even pause the music and change songs just like you'd do with any other music player.
FireTube is an excellent app that basically transforms the entire content of YouTube into your new music library. The best thing about it is that you can log in with your YouTube account and listen to your own custom playlists.

My phone said, in a nutshell "It is an application that recollects people activities for money"
I have been facing issue since one month, whenever I am searching songs or anything it's saying No result find, I have downloaded all latest version and this issue facing in my all android devices.
Why does a YouTube app need access to my device's camera? Some questionable permissions.
Very good, it runs very well on Galaxy S5, I can lock the screen and it keeps working, no ads, I can create a playlist and play it in mix mode, meaning before one ends it mixes with the next one.
