Any app that lets you listen to music in the background that is free ?

Is there any app which allows you to listen music in the background and it costs nothing ?
I have a AudioTube for years, it has been taken off the market for some time and I was unable to find any new ones.
Anyone uses some apps that can do it ?

Well, the first thing that comes to mind is Spotify. I don't use it much, but from what I know, it's that it is free to use and has options to pay for premium features. I was actually surprised to find songs on Spotify that i would've expected to find nowhere else but on YouTube, so if you're looking free background music, Spotify is definetly worth checking out.
