Anyone still not using Spotify (Android, iPhone and Windows Phone) or Deezer(Android, iPhone and Windows Phone) has another option for streaming music from their iPhone or iPad: YouTube.  The video portal has an extensive web music catalog that can be just as good as any other music streaming service. There's just one problem: although the mobile app for iPhone and iPad is quite well designed, when you minimize it, the song you're listening to stops playing.
There is, however, still a way to stream music from YouTube on your iOS device if you use YouTube through a browser like Safari or Chrome. The trick is to run the app in the background and replay the media from the control panel– I'll show you how to do it below.

1. Open YouTube in your browser

Open your mobile web browser (in this case Chrome for iOS), then go tohttp://youtube.com.

2. Search

Run a search in YouTube for the artist of your choice (in this example, Michael Jackson).
Note that many YouTube users upload entire albums. To find them quickly, type the name of the artist or the album followed by 'full album'. If you want more variety, you can do the same by searching for accounts which have playlists.
YouTube Michael Jackson

3. Select video

Select the video and hit play.YouTube iOS

4. View running apps

Tap on your iPhone or iPad's center button twice to view all apps running in the background. The sound will stop.

5. Access from Control Panel

Swipe through to the home screen, and open the control panel by sliding your finger from the bottom to the top. Where the Play icon is, you'll see the video that's playing. Tap on the Play icon to resume music.
Press play Chrome YouTube iOS
The music will start again, and when you swipe down to exit the Control Panel, you'll still be able to hear the music. You can continue using your device and other apps, or you can put your device to sleep, and the music will keep on playing.
Just like that, you'll be able legally and freely listen to thousands of songs on your iPhone or iPad. Once you get the hang of it, it'll only take a few seconds to move to the next song and enjoy hours of music from YouTube.
