How To Launch the default Music App in android to play a particular song?

I want to play a particular song in a url through the default media player

I am able to play it using Play song on default music player - android

but it is not opening the app fully to play it

Also i am able to open the music player with following code

Intent intent = Intent.makeMainSelectorActivity(Intent.ACTION_MAIN,Intent.CATEGORY_APP_MUSIC);


startActivity(intent);

How can i do both ?
