Music Listening On Locked Screen

[Jacekwww]

Hello
Dear all I have redmi note 2 with last soft 6.10.27 it is possible to listening music from youtube app or standard music app when i block the screen with button on side of phone ?
It's really important to lock screen put phone to pocket and make some exercises or work.
How to do it ?

Did you already tried to lock the running app via task manager (left button with 3 lines --> swipe down on the app (a closed lock appear)
This will keep the app running in the background even if the display is off

Thank You for Your answer
Really I didn't known this solution till this time.
If I lock the app (closed padlock is visible) and I press middle button to see phone menu music stop working, the same situation with lock button on right side of case.
Mayby I still make sth wrong ?
